Abstract
A kind of Piston Refrigerant Compreessor.The cylinder head of compressor has endoseptum and periphery wall, thus the compressor cylinder lid is divided into induction chamber and exhaust port.The length of the endoseptum length than periphery wall slightly is long, and therefore, when the cylinder head mount was gone to compressor housing, endoseptum was big for the pressure of cushion member for the pressure ratio periphery wall of cushion member.
Description
The invention relates to a kind of Piston Refrigerant Compreessor, particularly about a kind of structure that is used between the induction chamber of cylinder head and exhaust chamber, forming sealing.
In traditional Piston Refrigerant Compreessor, the side at compressor has cylinder block at least, and cylinder head is connected on an end of cylinder by valve plates and cushion member lid.Cylinder head is divided into two chambers like this, such as induction chamber and the exhaust chamber separated by outer circle wall and endoseptum.These wallboards be parellel and by the pad member contact with valve plates with obtain between induction chamber and the exhaust chamber, sealing between outside and induction chamber or the exhaust chamber.Usually, the length of these wallboards is identical.
In the above-mentioned compressor structure, cylinder head generally is connected on the compressor case by cushion member and valve plates by many bolts.These bolts isogonism on the cylinder head excircle is arranged and is run through outer wall section.Therefore, outer wall end face and next door end face are different with respect to the pressure of cushion member.And induction chamber is positioned at cylinder head outer circumferential periphery part, and then the pressure of the pressure ratio outside of induction chamber is relatively smaller, and therefore, the sealing between induction chamber and the outside can be guaranteed.And, the pressure height of the pressure ratio induction chamber of exhaust chamber, and the next door end face is low for the pressure of cushion member for the pressure ratio outer wall end face of cushion member.Therefore, the sealing between cushion member and the next door end face will be difficult to guarantee.Like this, the pressurized gas in the exhaust chamber just may leak in the induction chamber, and the result of its leakage will cause compressor efficiency to reduce.
Main purpose of the present invention just provides a kind of refrigeration compressor that has improved, and it can guarantee the sealing between induction chamber and the exhaust chamber.
Other purpose of the present invention provides a kind of refrigeration compressor that has improved compression efficiency through improving minutely.
A kind of Piston Refrigerant Compreessor according to the present invention comprises: a compressor housing is provided with the cylinder block with many cylinders in this housing; Many pistons, each in these pistons is to-and-fro motion in certain cylinder all; A valve plates has suction port and exhaust port with respect to cylinder arrangement separately on this valve plates; Also comprise cylinder head, have endoseptum and the periphery wall having determined suction chamber and discharged the chamber in the cylinder head, the length of endoseptum is more slightly longer than the length of periphery wall.
Other purpose of the present invention, the characteristics and the parties concerned can obtain profound understanding by the detailed description of the following embodiment of the invention and with reference to description of drawings.
Fig. 1 is the sectional view according to Piston Refrigerant Compreessor of the present invention.
Fig. 2 is the phantom of expression Piston Refrigerant Compreessor critical piece of the present invention.
Fig. 3 is the phantom along II among Fig. 2-the II line is cut open.
With reference to Fig. 1,2 and 3, there is shown a kind of according to Piston Refrigerant Compreessor of the present invention.Compressor has cylinder casing 10, is provided with cylinder block 11 in cylinder casing 10, also has protecgulum 12 and cylinder head 13.The inside of housing 10 is crank box 14 by the working space that cylinder block 11 and protecgulum 12 are limited.The solid of rotation 15 that is installed within the crank box 14 is fixedly mounted on the inner of live axle 16.Live axle 16 stretches out and by 17 rotatably supports of the needle bearing on protecgulum 12 from the core of protecgulum 12.Solid of rotation 15 is also by 18 supportings of the needle roller thrust bearing on protecgulum 12 internal surfaces.Rocker 19 is installed on the inclined-plane 15a of solid of rotation 15 by needle bearing 20.Rocker 19 is non-rotatably supported by the steel ball 21 that is placed in support member 22 1 ends.
Support member 22 comprises axle body 22a, has bevel gear 22C in its end, and has axial bore 22b in its other end, have at the center of bevel gear 22C one can embed steel ball 21 the seat groove.Support member 22 can endwisely slip but can not rotate, and the axle body 22a of support member is inserted into and forms supporting in the axis hole 23 that is formed in the cylinder block 11.The rotation of support member 22 stops by key (not shown) and keyway 23a.Spiral spring 24 is installed among the axis hole 22b of supporting member 22, and the outer end of this spring 24 contacts with spiral component 25, and like this, axle body 22a is pushed to rocker 19.The bevel gear 26 that is meshed with bevel gear 22C on the supporting member 22 is installed on the rocker 19, prevents that with this rocker from rotating.Steel ball 21 both seat is embedded in the seat groove at bevel gear 22C center, and also seat is embedded in the seat groove at bevel gear 26 centers, but so rocker 19 nutatings but be supported on un-rotatably on the steel ball 21.
In cylinder block 11 exterior edge faces, above cylinder head being installed in by cushion member 32,33 and valve plates 31 with many bolts 30.
The inside of cylinder head is divided into two cells by endoseptum 13b and periphery wall 13a, i.e. induction chamber 34 and exhaust chamber 35.
Endoseptum and periphery wall are parallel to axially from the cylinder head end plate and protrude and withstand on the liner 33.The length of endoseptum 13b is a little longer slightly than periphery wall 13a, therefore, endoseptum 13b just can separate induction chamber 34 and exhaust chamber 35 significantly, and when being installed to cylinder head 13 on the valve plates 31 with bolt 30 by liner 33, endoseptum 13b can not reduce with respect to the pressure of cushion member 33.Because when countercylinder lid 13 carries out fastening operation, be that the end face of endoseptum 13b is closely contacted with cushion member 33 at first, so the degree that is close between endoseptum 13b and the cushion member 33 is bigger than the degree that is close between periphery wall 13a and the cushion member 33.
The valve plates assembly comprises valve plates 31, many suction ports 36 that induction chamber 34 is connected with separately cylinder 27 have been formed thereon, with many exhaust ports 37 that exhaust chamber 35 is connected with separately cylinder 27, air-breathing spring valve (not shown), exhaust spring valve (not shown), be used to stop the keep plate 38 of discharging spring valve transition distortion, be used for air-breathing spring valve and exhaust spring valve and keep plate 38 are fixed to screw bolt and nut device 39 on the valve plates 31.Cylinder head 13 is fixed on the end face of cylinder block 11 by valve plates assembly and cushion member 33 with bolt 30.
In compressor operation, live axle 16 can be by any suitable drive power source, and such as motor car engine, solid of rotation 15 rotates with live axle 16, and therefore, rocker 19 is with steel ball 21 nutatings of the inclined-plane 15a rotation of solid of rotation 15.The result of rocker 19 nutatings makes each piston 28 to-and-fro motion.Therefore, in each cylinder, will carry out bleeding and compress repeatedly to the refrigeration gas.The cool cycles of refrigeration gas is by realizing with the suction port 40 of induction chamber 34 and exhaust chamber 35 UNICOMs and the cooling circuit that exhaust port 41 is constituted respectively separately on the cylinder head 13.
The present invention is described in detail with reference to preferred embodiment, but this is only as an example, the present invention is not limited to this.Be appreciated that every those skilled in the art of being familiar with are not exceeding scope involved in the present invention, promptly all can easily make various changes and modifications the present invention by claim of the present invention institute restricted portion.
