Description
Technical field
The present invention relates to a kind of compressor, the refrigerant gas in the refrigeration cycle such as this compressor compresses motorcar air conditioner relates in particular to a kind of valve arrangement of compressor.
Background technique
Disclosed compressor is suggested and is used for compression refrigeration gas in Japan Patent publication No. 3326909 (first correlation technique).According to the compressor of first correlation technique, this compressor comprises cylinder block, forms in cylinder block: the cylinder thorax; Crankcase is located at the front end of cylinder block; Suction chamber and discharge the chamber is located at the front end of cylinder block; Valve is located at the cylinder thorax, between suction chamber and the discharge chamber.This valve further comprises the valve plate with inlet hole and tap hole, inlet hole makes between each cylinder thorax and the suction chamber and is communicated with, tap hole makes each cylinder thorax and discharges between the chamber and is communicated with, and also comprises the so-called leaf valve formula suction valve of the cylinder thorax that is arranged in valve plate, and can be used to open and close inlet hole.
The rotation of the piston utilization axially supported live axle in crankcase that is held in each cylinder thorax and to-and-fro motion, thereby compression go into to suck refrigeration agent each cylinder thorax from suction chamber by inlet hole, and the refrigeration agent that will be compressed is sent into from tap hole and discharged the chamber.
When the operation of compressor when halted state starts owing to remain in the difference of the refrigerant volume in each cylinder thorax, after startup, the refrigerant pressure in the refrigeration cycle fluctuates immediately.Thereby problem has occurred, and compressor the suction pressure pulsation has taken place and produce noise in the vaporizer of refrigeration cycle, and is stable up to running.
The pressure of cylinder thorax inner refrigerant when also reducing the compressor halted state fast in order to solve top problem, the compressor that proposes in above-mentioned first correlation technique has reduced the generation of noise by a kind of relief passage, specifically can by rough surface forming and with the contacted valve seat of suction valve, be communicated with relief passage.
Simultaneously, Japanese Unexamined Patent Publication No 52-147302 (second correlation technique) has proposed a kind of valve arrangement of compressor, according to second correlation technique, relief passage comprises the thin plate of being located between suction valve and the valve seat, or comprise the groove that is provided with around inlet hole, be provided and be used for refrigeration agent is discharged to suction chamber from the cylinder thorax, in order to reduce pressure.
Summary of the invention
Yet when the rough surface that is provided with when valve seat had formed relief passage, the size of the relief passage that forms between suction valve and valve seat was unfixed.Thereby the amount of the refrigeration agent that is discharged from from a plurality of suction valves is uneven, therefore produces being still within the bounds of possibility of suction pressure pulsation.
Further, described in second correlation technique,, need on valve plate, to carry out high-precision machining in order to form this groove when when inlet hole is provided with groove.Therefore, it is difficult forming relief passage, and this will cause high manufacture cost.
When using thin plate, simple thin plate has when suction valve and thin plate bump, the danger of generation collision noise.
The object of the present invention is to provide a kind of compressor of being convenient to process, and have the gap (relief passage) that forms with uniform-dimension.
In order to reach top purpose, disclosed in the present invention compressor comprises: cylinder block has the cylinder thorax that holds piston; Crankcase is located at an end of cylinder block; Suction chamber and discharge the chamber is located at the other end of cylinder block; Valve is located between cylinder thorax and the suction chamber and cylinder thorax and discharging between the chamber; Valve plate is provided with described valve, and has the inlet hole that is communicated with cylinder thorax and suction chamber and be communicated with the cylinder thorax and the tap hole of discharge chamber; Suction valve is provided with described valve, is assemblied in the cylinder thorax side of valve plate, and suction valve comprises that flexible plate is can open and close inlet hole; Live axle, rotatable and axially support are used for reciprocally driven plunger in crankcase; Valve arrangement, wherein be formed with suction valve, suction valve has suction valve main body and counterpart, counterpart be integrally formed on the suction valve main body and towards the valve seat of inlet hole and inlet hole edge of opening can open and close inlet hole, and wherein be formed with the gap and form device, the gap forms at least one in valve plate and suction valve of device, by counterpart is isolated from valve seat within a predetermined distance, forms predetermined gap between counterpart and valve seat.
