Definitions
- Valve plate for piston compressors in particular for the generation of compressed air in motor vehicles
- the invention relates to a valve plate according to the preamble of claim 1.
- Valve plates for piston compressors which are provided in particular, but not exclusively, for the generation of compressed air in motor vehicles, consist, according to a known construction, of two individual plates, one of which is generally designed as a steel plate and the other as a cast plate containing coolant flow channels.
- the object of the invention is to simplify the production technology of valve plates or valve supports consisting of plate halves, the possibilities of adequate cooling by means of a coolant channel located in the valve plate, the shielding of the pressure bores or pressure openings from the action of heat and the design of the valve seats for the pressure holes are to be optimized.
- valve plate which consists of two individual plates each made of die-cast material, optimizes the manufacturing possibilities, since all mechanical processing can be saved, except for the machining of the sealing surface.
- split design consisting of die-cast plates also enables the most complicated cooling water routing, in particular to bring cooling water directly to the hottest point, namely to the pressure bores or pressure openings.
- the high-strength connection of both die-cast plates by gluing with sufficient sealing is guaranteed;
- These sleeves can be used to optimize the sealing strength in the area of the pressure openings.
- Steel rivets can also be provided, which are advantageously provided as tubular rivets both for mutually bracing the valve plate halves and for shielding the glued intermediate area of the two valve plate halves from the action of heat.
- Figure 1 is a sectional view of a valve plate according to the invention through two pressure openings
- Figure 2 is a top view of the suction side of the valve plate shown in Figure 1;
- FIG. 3 is an enlarged partial sectional view of the valve plate of Figure 1;
- FIG. 4 is a plan view of a valve plate according to a further embodiment of the invention, showing two valve catchers;
- Figure 5 is a sectional view of line V-V in Figure 4 showing the valve plate with steel rivets penetrating the pressure openings.
- the valve plate 1 according to the invention shown in FIG. 1 of the drawing consists of a die-cast plate 3 and a die-cast plate 5.
- the die-cast plate 3 faces the pressure side of the piston compressor, while the die-cast plate 5
- FIG. 1 as a sectional view of the valve plate, which runs in the area of two pressure bores or pressure openings 7, discloses that a coolant channel 9 runs in the valve plate.
- the coolant channel 9 is preferably located in the area of the pressure openings 7 and has inlet and outlet openings (not shown) for the coolant.
- the pressure openings 7 shown in the drawing in FIG. 1 in section and in top view in FIG.
- a suction lamella (not shown) is assigned to the suction openings 15 shown in the top view according to FIG. 2, which is held on the suction side of the valve plate in a manner not explained in detail and acts against the suction openings 15.
- the invention is not limited to the special embodiment of a valve or lamella construction for the pressure and suction side, although valve lamellae with simultaneous covering of several openings can be used preferably for both the pressure and suction side.
- the two die-cast plates 3 and 5 can be connected or sealed by coating or gluing in the area of the sealing surface 16. A metal seal coated on both sides between the die-cast plates can also be provided.
- a groove 17 for an elastomer seal on the suction and / or pressure side.
- the groove 17 is on the suction side, i.e. provided on the side of the die-cast plate 5 facing the cylinder.
- Such a groove with an elastomer seal can also be on the pressure side, i.e. be provided on the top of the die-cast plate 3; it is also possible to additionally provide a groove with an elastomer seal between the two die-cast plates.
- sleeves 19 are shown as insert parts in the pressure openings 7 of the valve plate 1. With the help of these sleeves, the hot compressed air is separated from the sealants or adhesives used, which are used to connect the two die-cast plates 3 and 5. In addition, the connection between the two die-cast plates is given a certain degree of stability.
- the use of such sleeves 19 proves to be of particular advantage since the highest temperature is in the passage area in question of the pressure openings 7. Set temperatures and with conventionally divided valve plates there was a risk of thermal destruction of the sealant.
- the inflow and outflow edges of the openings or bores passing through the valve plate are designed by rounding or profiling in such a way that flow losses are reduced to a minimum.
- FIGS. 4 and 5 show a valve plate according to a further embodiment according to the invention.
- the valve plate consists of two die-cast plates 3 and 5, which are provided with pressure bores or pressure openings 7.
- steel rivets 21 are inserted into the pressure openings 7 and braced against the plate halves in the course of the riveting process.
- the steel rivets therefore not only have the function of shielding the separating area between the plate halves from the heat of the compressed air generated, they also provide a holding and tensioning function against the two plate halves, which is particularly advantageous in the area of the pressure openings due to the considerable temperature differences.
- the steel rivets are designed as tubular rivets, which carry the rivet head located at the lower end in FIG. 5 and whose opposite end is shaped in a known manner in the riveting process.
- two valve catchers 23 are shown, which serve in a known manner to intercept the valve lamella (s) 25, which are also shown and cover the pressure openings 7.
