Definitions
- the invention relates to a device for a fuel supply system according to the preamble of claim 1.
- Such a device is known from DE 44 02 224 AI.
- This device has a feed pump which is arranged in the storage container and can be introduced through an opening in the storage container.
- the opening in the storage container can be closed by means of a closure part on which a pressure regulator is arranged.
- the pressure regulator has a pressure chamber which has a connection to the pressure side of the feed pump, to the internal combustion engine and to a relief line.
- the closure part has a flange-like base body consisting of plastic and closing the opening.
- a recess is formed in the base body, into which a connection piece, which forms the connection between the pressure chamber and the relief chamber, and which is formed in one piece with the base body, projects.
- the depression of the base body is to form the pressure chamber with an elastically deformable membrane covered, which cooperates directly with the face of the nozzle as a seat.
- the membrane is acted upon by a spring towards the nozzle, and when a certain pressure in the pressure chamber is exceeded, the membrane releases the nozzle to connect the pressure chamber to the relief chamber.
- the membrane is attached to the body. In the known device, the membrane is inserted into the recess, the spring is attached and then the membrane is stretched together with a cover against the base body.
- the holding element has a flange on which free ends bent over to the outside are formed.
- the flange is arranged to a collar of the base body, whereby an outer edge of the membrane is clamped.
- the free ends of the flange engage behind hooks arranged on the collar, as a result of which the flange of the holding element is arranged under tension to the base body and clamps the membrane.
- this configuration has the disadvantage that the hooks of the recess have to absorb the clamping force of the spring, which acts on the membrane, so that the membrane closes the connection piece to the pressure chamber. The large holding forces that occur cannot be adequately absorbed by the hooks.
- the device according to the invention for a Kraft ⁇ toffver ⁇ orgung ⁇ strom with the features according to claim 1 has the advantage that a simple and safe assembly of the membrane to the base body is carried out with little effort, wherein an exact positioning of the membrane to the base body can be achieved. This enables a tight and durable connection to the base body, as a result of which the pressure space can be safely separated by the membrane.
- By attaching the spring washer to the base body to fix the membrane it is possible that the tension force of the spring washer that is under pretension and is arranged relative to the base body and holds the membrane can only be determined by the pretensioning of the spring ring.
- this arrangement has the advantage that, after the membrane has been positioned relative to the base body, the membrane can be clamped to the base body simply by placing the spring ring, which preferably engages in the edge region of the membrane, without twisting forces or other forces that may result a shift or impairment of the position of the membrane to the base body can take place.
- the spring ring fixing the membrane to the base body has the advantage that tolerance compensation is possible due to the resilient arrangement or the arrangement under pretension, so that the membrane is arranged securely to the base body.
- the Membrane is firmly clamped against the base body before a spring pressing against the membrane is placed. This prevents the spring from undesirably shifting the diaphragm laterally.
- the connecting piece through which the fuel return is guided can be injected with an injection tool together with the base body as a plastic part. This has the advantage that no additional effort is required in the manufacture of the base body for the manufacture of the nozzle.
- the tensioning element is designed as a plate-spring-shaped ring.
- This ring which is made of metal, allows the diameter which limits the effective area of the membrane to be determined, thereby preventing an increase in the effective area of the membrane during use of the device, which, when the membrane is used in a pressure regulator, results in a decrease in the Rule pressure could express.
- the pressure space of the device remains tight to the outside during the entire operating time of the device.
- the elastic prestressing of the installed spring ring gives the advantage that the membrane is pressed against the base body with sufficient force even when the device is in operation for a long time, regardless of any signs of settling of the base body, which is preferably made of plastic.
- the spring ring in the region of its Clamping point has a cam-shaped elevation facing the membrane, which engages in a congruent recess of the clamping point provided in the base body.
- the spring ring acting as the tensioning element has an annular collar at its free ends, so that the spring ring is cup-shaped in cross section.
- the clamping force can be increased if the plate-spring-shaped ring is arranged on the base body.
- the plate-spring-shaped ring, the sections of which form the cup-shaped cross section are arranged at an angle of greater than 90 ° can have an additional clamping force on the section arranged in the clamping point, since the section forming an annular collar is on the section assigned to the membrane can have an additional force.
- the spring ring can be inserted freely into the recess from above and can be fastened under pretension. This can advantageously be done via a snap connection. Furthermore, it can advantageously be provided that a spring-like ring element, in particular a snap ring, can be inserted into a groove provided on the base body. Furthermore, it can advantageously be provided that the free ends of the recess adjoining the recess Basic body can be provided by reshaping, such as flanging, caulking or the like, clamping the membrane and arranging the spring ring under pretension.

- the latching connection 71 according to FIG. 4 is formed by a circumferential annular collar 70 which has hooks 72 which spring radially inwards to the longitudinal axis of the connecting piece 45 and which engage behind the spring ring 54 in its fixed position.
- the hook 72 as well as the base body 30 are preferably made of plastic, the hook 72 being designed to be resilient.
- the base body 30 and the hooks 72 can be produced together in a common injection mold without great effort.
- the base body 30 and the hooks 72 are an integral component. Due to the multiple radial slots of the collar 70 shown in FIG. 4, the hooks 72 can yield so far radially outwards during the assembly of the spring ring 54 on the base body 30 that the spring ring 54 can be snapped into place. After pressing the spring washer 54 against the Shoulder 55 resiliently spring hook 72 radially inward and thereby hold spring ring 54 against shoulder 55.
- the height of the second section 59 of the spring ring 54 is matched to the distance between the shoulder 55 and the radially inwardly projecting hook 72 so that the spring ring 54 is deformed in the assembled state, which leads to a pretension in the spring ring 54 leads, so that the first section 56 of the spring ring 54 tensions the outer peripheral region of the membrane 49 against the shoulder 55 of the base body 30.
- the spring ring 54 can be divided into a first section 56 and a second section 59. With its first section 56, the spring ring 54 presses the membrane 49 against the shoulder 55, as a result of which a clamping point
- the first section 56 of the tensioning element 54 has a cam-shaped elevation 58 which engages in a congruently formed circumferential depression 60 in the shoulder 55.
- the elevation 58 can improve the sealing of the pressure chamber 44.
- the depression 60 in the shoulder 55 of the base body 30 can also be less deep than the height of the elevation 58. This ensures that in the region of the elevation 58 between the membrane 49 and the base body 30 and also between the membrane 49 and the circumferential elevation
- the elevation 58 on the base body 30 and the congruent depression on the spring ring 54 it is advisable to provide the elevation 58 on the spring ring 54 and the depression on the base body 30.
- the first section 56 of the spring ring 54 is followed by the second section 59, which has a cup-shaped configuration in cross section with the first section 56.
- the first section 56 is in the untensioned state, that is to say before the installation of the spring ring 54 in the recess 63, according to FIG. 3 to the second section 59 at an obtuse angle.
- the first section 56 is deformed to the second section 59 of the spring ring 54 in such a way that these sections 56, 59 approach a right angle. This can result in a further increase in the clamping force at the clamping point 57.
- the spring 53 is placed on the plate 52.
- an insert 61 is arranged at the end of the spring 53 facing the reservoir 12.
- the membrane group 48, the spring 53 and the insert part 61 arranged for the spring 53 are surrounded by a holding element 62 and fastened to the base body 30.
- the holding element 62 is designed as a cap. This holding element 62 has an opening in a longitudinal axis in which the insert 61 arranged i ⁇ t. Seen in cross section, the holding element 62 is essentially U-shaped and can be inserted into a slot 66 of the base body 30.
- Barbed elements 68 are arranged on an inner or outer side of the cylindrical outer surface 67 of the holding element 62, which enable the holding element 62 to be easily and quickly assembled to the base body 30. By simply pushing it on, there can be a secure arrangement of the holding element 62.
- the holding element 62 can be made of both plastic and metal.
- the holding element 62 preferably consists of deep-drawn steel.
- the holding element 62 is attached to the base body 30.
- the inside of the outer surface 67 is located close to the resilient hook 72 of the base body 30 or touches the outer circumference of the hook 72, so that the hook 72 of the snap connection 71 on the base body 30, which holds the spring ring 54 hold, after mounting the retaining element 62 can no longer move radially outward, so that, even when the diaphragm 49 and the spring ring 54 are loaded by a relatively high pressure in the pressure chamber 44, the hooks 72 on the base body 30 hold the spring ring 54 securely .
- This enables a very stable locking connection 71, even if no particularly high-strength and therefore expensive plastic is used for the base body 30.
- FIG. 5 shows an alternative embodiment of the ratchet connection 71 to FIG. 4.
- the annular collar 70 of the latch connection 71 is formed continuously and has a hook-shaped profile in cross section, whereas the spring ring 54 has a second section 59 which passes through a plurality of individually deflectable and radially inwardly resilient tabs 73 is formed. Otherwise, the statements made in relation to FIG. 4 apply.

- this embodiment has a spring ring 154 which is of simpler design and an alternative fastening of the spring ring 154.
- the spring ring 154 is shown in the untensioned state before installation in FIG. 7 and is designed similarly to a known plate spring.
- the spring ring 154 like the spring ring 54 in FIG. 2, has the cam-shaped elevation 58.
- the function of the elevation 58 corresponds to that as described with reference to FIG. 2.
- the spring ring 154 is fastened in the recess 63 via a ring element 81 which can be inserted into a groove 82 in the base body 30. Similar to a so-called snap ring, the ring element 81 is slit at one point on its circumference and can be installed in the groove 82 by radial compression. After installation, the ring element 81 springs radially outwards and thereby holds itself in the groove 82.
- the spring ring 154 is removed when the ring element 81 is assembled Its original, unstressed position is deflected such that it has almost a horizontal course, so that the greatest possible elastic tension can be achieved in the spring ring 154
- the spring ring 54 shown in FIG. 2 and vice versa can also be used.
- FIG. 8 shows a further alternative embodiment of fastening the spring ring 154 to the base body 30 in order to fix the membrane 49 to the base body 30 at the clamping point 57.
- the tensioning element 154 is placed on.
- the spring ring 154 is attached to the peripheral edge of the recess 63.
- the spring ring 154 has the shape shown in FIG. 7.
- the spring ring 154 is inserted into the recess 63 so that the inner circumference of the spring ring 154 bears against the shoulder 55 before the flanging or caulking.
- the outer circumference of the spring ring 154 is pressed against the shoulder 55 of the base body 30 using a tool which is in the form of a stamp. After crimping or caulking the end 76, the deformation of the spring ring 154 is retained, so that a pretension arises which securely clamps and holds the membrane 49 between the shoulder 55 of the base body 30 and the spring ring 154.
- tensioning element or spring washer 54 or 154 and the types of fastening according to FIGS. 2, 4, 5, 6 and 8 can be combined with one another as desired and can have analogous modifications.
- the device according to the invention for a fuel supply system is designed as a pressure regulator, for example, and in which the base body 30, in addition to its task of holding the membrane 49 and the spring ring 54, also covering the opening 20 of the storage container 12 serves.
- the pressure regulator can also be arranged at any other point in the fuel supply system.
- the base body 30 can also be, for example, a fuel distribution pipe in the area of the internal combustion engine, the feed lines to the individual fuel injection valves also branching off from the fuel distribution pipe.
- FIG. 9 also shows a device for a fuel supply system with a membrane 49, which is clamped in its edge region with a spring ring 54 that is pre-tensioned and held on the base body 30.
- the pressure chamber 44 is connected to a fuel connection 84. Fuel can be supplied to the pressure chamber 44 or fuel can be removed from the pressure chamber 44 via the fuel connection 84.
- the device shown in FIG. 9 is used, for example, for smoothing pressure pulsations of the fuel in the pressure chamber 44 or in the fuel connection 84. This device is therefore usually referred to as a pressure damper.
- this device can, however also be dimensioned such that the membrane 49 has a relatively large working stroke, so that the device can absorb a corresponding amount of fuel when the pressure rises, which the pressure chamber 44 then releases again when the pressure in the fuel drops, which is why, with appropriate dimensioning, this device is also referred to as fuel storage.
