Abstract
The invention discloses a valve plate of a refrigerant compressor. The port plate has a groove on its outer surface facing the piston, the shape and depth of which is close to the suction valve supported in the groove to accommodate the suction valve during compression. Compressor efficiency is improved due to the reduced dead space around the suction valve edge.
Description
The relevant a kind of coolant compressor of the present invention has some compression cylinders and reciprocal movable piston, the specifically thrust plate of relevant coolant compressor in cylinder in its compression cylinder cylinder body.
In existing coolant compressor, a cylinder body is arranged, a front case and a cylinder cap.A crank chamber is between front case and cylinder body.There is a rotor to be placed in the crank chamber, is connected with a live axle is terminal, and, rotatably is installed on the front case by a needle bearing.Live axle rotatably utilizes a bearing, is installed in the front case.
The shaking disk that an annular is arranged by a needle thrust bearing, leans against on the inclined surface of rotor.Have a bevel gear and shaking disk to fix, and mesh with a bevel gear, the latter has a cylindrical part.Bevel gear is around a steel ball engagement that is placed between them.Cylindrical part is placed in the passage in the cylinder body.Cylindrical part can be done axial activity, but can not rotate.Cylindrical part is also by the bevel gear pushing of a spring to shaking disk.The rotation of shaking disk is owing to the engagement of bevel gear and bevel gear is stoped, so shaking disk only rocks and do not rotate.
Some compression cylinders are arranged in cylinder body.Be placed with a piston that can in cylinder, slide in each compression cylinder,, be connected with the circumference of shaking disk by the spherical coupling piece of interlinking lever end.Each spherical coupling piece can be with respect to part of the recess on the shaking disk and piston activity.
On two surfaces of thrust plate, pad is arranged.A cylinder cap is arranged, be fixed by bolts on the other end of cylinder body, bolt passes through from thrust plate, and thrust plate is fixed between cylinder body and the cylinder cap.A suction chamber is arranged,, have a discharge side to form in the center portion of cylinder cap along the periphery formation of cylinder cap.On thrust plate, form the inlet hole of some perforation thrust plates, fluid and suction chamber in each compression cylinder are connected.On thrust plate, also form the tap hole of some perforation thrust plates, the fluid of each compression cylinder and discharge side are connected.Pad have perforate and inlet hole and tap hole over against.
A suction valve is arranged, be placed on thrust plate on the end face of compression cylinder, an expulsion valve is arranged, be placed on another end face of thrust plate.Thrust plate is fixed between suction valve and the expulsion valve with a bolt, valve be parked in thrust plate flat outer surface above.There is a plate to support expulsion valve, also is bolted on the thrust plate with one.
Suction valve has a structure shape that is generally star, and some tips are arranged above, respectively stretches at one above the inlet hole, and is open or close corresponding hole.Expulsion valve is also similar, and star structure shape is roughly arranged, and some tips are arranged above, respectively stretches at one above the tap hole, and is open or close corresponding tap hole.
Because suction valve and expulsion valve fixing on thrust plate just is parked in the top of the flat outer surface of thrust plate, the increase of piling up the material thickness that causes the thrust plate outer surface of valve simply.Thrust plate on a side of compression cylinder, the top around the outer surface of the edge of suction valve and thrust plate produces a quiet space or wasted space.This quiet space and because the volume-variation that the reciprocal activity of piston causes is irrelevant, just because in the maximum compression stroke, in the lowest power volume, increased additional volume, institute so that compression ratio descend.The result descends the compression efficiency of this compressor.
Purpose of the present invention is to propose a kind of valve and thrust plate that improves the coolant compressor of compression ratio.
Why above-mentioned purpose of the present invention and other purposes can obtain, and are by proposing a kind of coolant compressor, a fore shell is wherein arranged, a cylinder body and the cylinder cap that a suction chamber and a discharge side are arranged that some compression cylinders are arranged along circumference.There is a live axle to support by fore shell.Place a piston in each compression cylinder, but be connected reciprocating with live axle in the mode of transmission.A thrust plate is arranged between compression cylinder and cylinder cap, and an inlet hole and a tap hole are arranged, make fluid and suction chamber and discharge side connection in each compression cylinder at each cylinder place.There is a suction valve to stretch on each inlet hole, inlet hole is opened or closed.Flow-distributing valve has a groove, forming on the outer surface of piston of it.In order when compressing suction valve to be contained in the groove, groove has the identical shape of the suction valve of making peace greatly and the degree of depth.
Other purposes of the present invention, read hereinafter desirable embodiment with reference to being described in detail that accompanying drawing is done characteristics and aspect, just can understand to some extent.
Fig. 1 is in one embodiment of the invention, the axial front elevation towards cylinder body one side of thrust plate and suction valve.
Fig. 2 is the axial front elevation towards cylinder cap of a thrust plate and an expulsion valve.
Fig. 3 is the thrust plate among Fig. 1 and Fig. 2, a sectional view of suction valve and expulsion valve.
Fig. 4 is the local amplification view of coolant compressor of the present invention, is illustrated in the relation of piston and thrust plate and suction valve in the compression process.
Fig. 5 is a sectional view of existing coolant compressor.
Fig. 6 is the axial front elevation of thrust plate and compressor casing one side of suction valve in Fig. 5.
Fig. 7 is the axial front elevation of thrust plate and compressor cylinder cover one side of expulsion valve in Fig. 5.
Fig. 8 is the thrust plate sectional view shown in Fig. 5.
Fig. 9 is the local amplification view of the coolant compressor among Fig. 5, is shown in the relation of piston and thrust plate and suction valve in the compression process.
Figure 10 is the local front elevation that amplifies of the coolant compressor shown in Fig. 5, diagram suction valve and pad.
Because the general construction of compressor of the present invention is identical with the structure of coolant compressor shown in Figure 5, therefore only the improvement thrust plate proposed by the invention and the structure of suction valve are narrated.
About Fig. 1,2,3 and 4, to the parts of compressor of the present invention, all represent with the number of marking on a map that adds suffix A.As shown in the figure, thrust plate 30A of the present invention, it on the outer surface of piston 26A, have groove to form.On thrust plate 30A, form to connect the inlet hole 35A and the tap hole 36A of thrust plate, fluid among the compression cylinder 25A and suction chamber 33A and discharge side 34A are communicated.Groove 1A and the suction valve 38A that is roughly star have near identical shape, its size near or be slightly larger than suction valve 38A.The deep equality of groove 1A in or slightly be deeper than the thickness of suction valve 38A.Therefore the outer surface of suction valve 38A is except that groove (A) is located, all almost concordant with the remaining part of thrust plate 30.
Be described in detail as above with regard to desirable embodiment about the present invention, but only as an example, and invention is not limited.Intelligible is all this special dealers that is good at, and very easily makes various other variation and modification and do not exceed the present invention's scope.
