Definitions
- the present invention relates to a device according to the preamble of claim 1.
- Compressors of this type which compress gases by means of a piston moved by an electromechanical or other type of drive are known.
- a piston driven by a crank or a connecting rod is set in a reciprocating motion in a cylinder and thereby causes the gas to compress on one side of the piston.
- Such devices exist in various designs and sizes and are used in a wide variety of fields.
- Drive mechanisms of different types and performance are also used. Difficulties arise in particular with weaker drives, for example with systems operated by batteries, which have to set a piston in motion against an already existing initial counterpressure.
- the object of this invention is to propose a device of the type mentioned at the outset or a piston compressor which, with a simple and reliable design, can start up against significantly higher back pressures than previously known embodiments.
- a quiet movement and longevity of the piston and the seal in the cylinder are achieved by the design features according to claim 2, 3 and / or 10.
- An advantageous and effective embodiment of the sealing mechanism is described in the features of claims 4 to 6.
- the seal is advantageously stored and guided according to claims 7, 8 and / or 9.
- the leaks advantageously formed according to the features of claim 11 have a small cross-sectional area compared to the cylinder cross-section or the stroke volume of the piston, with which the leakage losses after start-up are minimal being held.
- the positioning, shape and type of formation of the leaks according to claim 12 allow design-related variation options, depending primarily on the type and size of the piston or the entire compressor device.
- the leaks are formed in the inner region of the support disk and the guide disk, they are arranged in alignment and enable the defined gas passage through this feature described in claim 13.
- the cuts in the seal described in the features of claims 14 to 22 and their number, design and distribution improve the elasticity and the friction behavior of the seal and thereby bring about an optimal sealing and compression behavior.
- the piston is essentially sealed in the cylinder. A gas passage from
- Working space in the unpressurized room is essentially determined by the leaks.
- Fig. 1 shows a schematic representation of a compressor arrangement including power supply, drive and hose connections.
- Fig. 2 shows an overview of the power transmission and compression mechanisms.
- Fig. 3 shows a schematic sectional view of the piston located in the cylinder.
- Fig. 4 shows an alternative embodiment of a piston with leaks.
- Fig. 5 shows a cross section through a seal.
- Fig. 6 shows a plan view of an annular seal with cuts.
- an electromechanical drive 1 is fed via a battery, not shown, which is connected via a cigarette lighter plug 9 and a cable 10 to a control console 12 and via a further cable 13 to the drive or
- Electric motor 1 is connected.
- the power supply can be switched on and off with a rocker switch 11 located on the console 12.
- Compression mechanism is actuated via this drive 1 and the working medium, in this case air, is conveyed via a pressure hose 5 fastened with a clamp 4 to the outlet 22 of the cylinder 2, via a manometer 6 for pressure control and via an outlet 8 to the destination object, e.g. Car tire, pressed.
- the working medium in this case air
- Cylinder 2 and the piston 20 limited volume of the working space 26 in front of the piston 20 or the volume of the unpressurized space 24 behind the piston 20 changed.
- a Check valve 27 prevents the air forced out of the outlet 22 from flowing back into the working space 26.
- the piston 20, shown enlarged in FIG. 3 and located in the cylinder 2, comprises a plate-shaped guide disk 16 fixed to the push rod 14 on its head or work space side 26, and also a fixed to the push rod 14 and possibly permanently connected to the guide disk 16 in the inner region plate-shaped support disk 15 on its rear side or its side facing the unpressurized space 24 and an annular seal 17 lying against the wall of the cylinder 2.
- the guide disk 16 is in the inner region, a central part 28, preferably running parallel to the wall of the cylinder 2, and a terminal part peripheral flange 25 'articulated.
- the support disc 15 is also divided into an inner region, a middle part and a terminal peripheral flange 25.
- the height of the seal 17 is between the two peripheral flanges 25, 25 'of the support disc 15 and the guide disc 16 in the peripheral region of the piston 20. Between the seal 17, the support disk 15 and the guide disk 16 or their peripheral flanges 25, 25 'there is a free space 27.
- the surface of the seal 17 facing the inner wall of the cylinder 2 is concave outwards, in particular with a circular curvature, around the slightly oscillating one
- the seal 17 has on its side facing the working space 26 in
- Cross-section narrow head region 40 and on the side facing away from the working space 26 a foot region 41 which is wider in cross-section.
- a recess 43 is advantageously formed on the inner surface of the seal 17, into which a spring ring 18 is inserted, in particular firmly and preferably with a snug fit.
- This spring ring 18 is accordingly between the middle part 28 of the guide disk 16 and the head region 40 of the seal 17.
- the spring ring 18 can be moved up and down during a stroke movement of the piston 20 along or in front of this middle part 28 of the guide disk 16, its upward movement or its upward travel is limited by the peripheral flange 25 'of the guide disk 16.
- the seal 17 is pressed radially outward or against the side wall of the cylinder 2 by means of this spring ring 18 and prevents undesired gas passage there.
- a resilient clamping ring can also be used. In both cases, however, air can pass between the free space 27 and the work space 26 at this point.
- the height H of the seal 17, measured in the direction of movement of the piston 20, is less than the distance A measured between the inner sides of the peripheral flanges 25, 25 'of the support disk 15 and the guide disk 16. Accordingly, the movement amplitude of the seal 17 is based on the difference D. limited between the height H of the seal 17 and the distance A of the peripheral flanges 25, 25 'of the support plate 15 and the guide plate 16.
- the seal 17 consists of a largely heat-stable and / or largely abrasion-resistant polymer, in particular with good running and sliding properties, preferably polytetrafluoroethylene (PTFE, Teflon) or polytetrafluoroethylene compounds, and can optionally be combined with carbon or carbon fibers and / or particles in one Proportion of 10 to 20% by weight, preferably from 15 to 25% by weight, of the PTFE or PTFE compound weight can be reinforced.
- the number of leaks 19, as well as their shape or cross-sectional shape depends on the power of the drive mechanism, the amount of the initial counterpressure, the size and type of the compressor device, the shape of the piston, etc.
- the leaks 19 can be caused by bores, milled recesses, Sinkings or the like are formed, the shape of which is also determined by the production method. Accordingly, the leakages 19 can be round, angular or even irregularly shaped in cross section.
- the total cross-sectional area of the at least one leakage 19 is between 0.005 and 0.1 mm 2 , preferably 0.01 and 0.06 mm 2 , per cm 3 of stroke volume of the piston 20.
- the formation of the leaks 19 can take place in the support plate 15 and / or the guide plate 16, both in the outer regions, that is to say in the peripheral flanges 25, 25 ', in particular in the peripheral flange 25 of the support plate 15, and in the inner regions, whereby to It should be noted that, when formed in the firmly and flatly connected inner regions of the disks 15, 16, the leaks 19 are advantageously arranged in alignment. Furthermore, there is the possibility of forming leaks in the entire area of the seal 17, in particular in the end face of the seal 17 facing the inside of the peripheral flange 25 of the support disk 15.
- FIG. 4 An alternative embodiment of a compression mechanism with startup relief is shown in FIG. 4.
- a piston 32 driven by a push rod or piston rod 14 is moved back and forth in the cylinder 2.
- This piston 32 divides the cylinder 2, as in FIGS. 2 and 3, into a head-side working space 26 and a pressure-free space 24.
- An annular seal 33 which lies tightly against the wall of the cylinder 2, is intended to prevent gas from passing through at this point prevent.
- In the piston 32 there is at least one defined leakage 19 with a small cross-sectional area compared to the cross-sectional area of the piston 32 or the cylinder 2 as well a suction opening 38, which can be closed with a check valve 37, is formed with a larger cross-sectional area.
- the check valve 37 closes the passage opening 38. Only the leakage 19 allows a low defined gas passage, which reduces the pressure existing in the working space 26 or acting on the piston 32 and thus realizes the start-up relief.
- the air is pressed to the destination object via an outlet 22 located in the wall of the cylinder 2 via a further check valve 37 '.
- the check valve 38 opens and allows free gas passage through the passage opening 38 and thus a rapid wake of "fresh air" from the unpressurized space 34 under the piston into the working space 26.
- the check valve 37 ' closes and prevents the back flow Air from the destination object into the work space 26.
- the above-mentioned essentially applies to the shape and configuration of the leak (s) 19.
- the leakage can also be formed in the valve 37.
- FIG. 5 shows a cross section through the seal 17.
- the head area 40 there are cuts 45 trained. Regarding the characteristics of the cuts 45, it should be noted that the cuts 45 are made without material removal, i.e. not milled, sawn or the like. become.
- the cuts 45 extend, starting from the upper end face of the head region 40 of the seal 17, at least to the beginning of the contact region 44 of the seal 17 with the inner wall of the cylinder 2, which in practice is due to the compression of the seal 17 against the wall of the cylinder 2 or by the tumbling movements of the piston 20.
- the cuts 45 extend from the upper end face of the head region 40 of the seal 17 to the theoretical contact line 42 of the concave seal 17, which is geometrically determined in FIG. 5, with the inner wall of the cylinder 2.
- the cuts 45, starting from the upper end face of the head region 40 of the seal 17, extend at least to the lower end of the recess 43.
- the cuts 45, measured from the upper end face of the head region 40 of the seal 17, extend to the beginning of the foot region 41 of the seal 17, that is to a maximum depth T.
- the cuts 45 completely penetrate the head region 40 of the seal 17.
- the preferably 6 to 12, in particular 8 to 10, here 9 cuts 45 are distributed along the circumference of the annular seal 17 and at equal distances from one another and are inclined relative to the radius R of the seal 17 in the same direction, preferably at an angle a between 30 and 80 °, especially between 40 and 70 °.
- the surfaces of the cuts 45 are flat and are aligned perpendicular to the plane spanned by the seal 17.
- the cuts 45 are advantageously identical to one another or have the same shape or dimensions. Leakage is understood to mean a constantly open (gas) passage connection between the space in front and behind the piston.
