Definitions
- the invention relates to a valve plate according to the preamble of claim 1.
- Valve plates for piston compressors which are particularly, but not exclusively are provided for the generation of compressed air in motor vehicles exist according to a known construction from two individual plates, one of which in generally as a steel plate and the other containing coolant flow channels Cast plate is formed.
- JP-A-59 208 181 discloses a valve plate for a compressor which consists of two interconnected plate halves. With this valve plate, the lines belonging to the valve elements after connecting the two Shaped plate halves.
- the object of the invention consists of plate halves to simplify existing valve plates or valve supports in terms of production technology, the possibilities of adequate cooling by means of a in the valve plate located coolant channel, the shielding of the pressure holes or pressure openings against exposure to heat and the design of the valve seats for the Pressure holes are to be optimized.
- valve plate By designing the valve plate from two each made of die-cast material existing single panels, the possibilities of production are optimized, except for the sealing surface machining saves all mechanical processing can.
- the split design consisting of die-cast plates also enables most complicated cooling water routing, especially to direct cooling water to the hottest point, namely to lead to the pressure holes or pressure openings.
- the high-strength connection of both die-cast plates by gluing adequate sealing is guaranteed; to optimize the tightness in the The area of the pressure openings can be inserted into these sleeves.
- Steel rivets can also be provided, which are more advantageous as tubular rivets Way both for mutual bracing of the valve plate halves as well Shielding the glued intermediate area of the two valve plate halves against the effects of heat.
- grooves are possible on both the pressure side and the suction side to be provided for elastomer seals, whereby the elastomer seals face each other able to seal the cylinder or the cylinder head. Even between the Both plates can have elastomer seals in grooves.
- the valve plate 1 shown in Figure 1 of the drawing according to the invention from a die-casting plate 3 and a die-casting plate 5.
- Die-casting plate 3 is the Pressure side of the piston compressor facing, while the die casting plate 5 is provided on the suction side.
- the die-cast plate 3 and 5 each consist of one high-strength aluminum alloy, with a special due to the existing cast skin high resistance is achieved.
- all mechanical processing with the exception sealing surface machining (both surfaces) can be saved.
- FIG. 1 as a sectional view of the valve plate, which in the region of two pressure bores or pressure openings 7, reveals that a coolant channel in the valve plate 9 runs.
- the coolant channel 9 is preferably in the area of the pressure openings 7 and has (not shown) inlet and outlet openings for the coolant.
- the in the drawing in Figure 1 in section and in Figure 2 in Printing openings 7 shown in plan view is one (not shown) assigned pressure lamella, which is compared to the in Figure 3 in Enlarged sectional view shown valve seats 11 moves and each in Area of bores 13 held by means of (not shown) fasteners is.
- suction lamella which is not detailed in detail explained way is held on the suction side of the valve plate and opposite Suction openings 15 acts.
- the invention is not special Embodiment of a valve or lamella construction for the pressure and suction side fixed, albeit valve fins with simultaneous coverage of several Openings for both the pressure side and the suction side are preferably usable.
- the two die-cast plates 3 and 5 can be coated or glued be connected or sealed in the area of the sealing surface 16. Also one metal gasket coated on both sides between the die-cast plates can be provided his.
- a groove 17 for each on the suction and / or pressure side to provide an elastomer seal.
- the illustrated embodiment is the groove 17 on the suction side, i.e. at the Cylinder-facing side of the die-cast plate 5 is provided.
- Such a groove with an elastomer seal can also be on the pressure side, i.e. at the top of the Die casting plate 3 may be provided; it is also possible to have a groove To provide an elastomer seal between the two die-cast plates.
- sleeves 19 are inserted in FIG the pressure openings 7 of the valve plate 1 shown.
- these sleeves hot compressed air separated from the sealants or adhesives used, which are used for Connection of the two die-cast plates 3 and 5 are used.
- the Connection of the two die-cast plates gives a certain degree of stability.
- the use of such sleeves 19 proves to be of particular advantage, since in the passage area of the pressure openings 7 in question the highest temperatures adjust and with conventionally split valve plates the risk of thermal Destruction of the sealant existed.
- the inflow and outflow edges of the openings or through the valve plate Holes i.e. the pressure openings and the suction openings, are through Rounding or profiling designed so that flow losses on a Minimum be reduced.
- valve plate 4 and 5 is a valve plate according to a further embodiment shown according to the invention.
- the valve plate consists in a corresponding manner two die-cast plates 3 and 5, which with pressure holes or pressure openings 7th are provided.
- the sleeve 19 of the arrangement of Figure 3 are in the Pressure openings 7 steel rivets 21 used and by way of the riveting process braced against the plate halves. So the steel rivets don't just have them Function, the separation area between the plate halves opposite the To shield heat from the compressed air generated, they also convey one Holding and tensioning function compared to the two plate halves, which in particular in the area of the pressure openings due to the considerable temperature differences is of particular advantage.
- the steel rivets are shown as pipe rivets formed, which carry the rivet head located at the lower end in Figure 5 and the opposite end formed in the riveting process in a known manner becomes.
- FIGS. 4 and 5 there are two valve catchers 23 shown, which in a known manner to intercept the also shown, serve the valve openings 7 covering valve openings 7.
