Background technique
Cylinder head is essential part in refrigeration compressor, and the air-flow of the mechanical moving element discharge in compressor is first
Cylinder head is introduced into drain by cylinder head again；Compressor air-discharging pulsation is to cause an important factor for compressor noise is with vibration,
Throttling is usually taken or increases exhaust chamber and pulses to reduce, and currently marketed cooler compressor cylinder head usually only one
A exhaust chamber and it is not provided with gas flow, cylinder head itself does not influence the inhibitory effect very little of exhaust gas pulses substantially.
Summary of the invention
The purpose of the present invention is to cylinder head itself to the inhibitory effect very little of exhaust gas pulses, does not have substantially influential
Problem provides a kind of noise reducing type cylinder head of rotor-type compressor, inhibits the effect of exhaust gas pulses good, noise reduction effect is obvious.
Concrete scheme of the invention is: a kind of noise reducing type cylinder head of rotor-type compressor, including lid, sets among lid
There is crankshaft hole, lid bottom periphery is equipped with sealing surface, and the circular bar being equipped at crankshaft hole towards bottom surface, annular are located on the inside of lid
The exhaust chamber of a circle sealing is formed between muscle and lid, is equipped with a sealing bar, sealing bar one end connection cover in exhaust chamber
Body sidewall, other end connection circular bar separate exhaust chamber, and sealing bar side is equipped with the air exit being connected to exhaust chamber,
The gas vent of the exhaust chamber face valve board assembly of the sealing bar other side, refrigerant are discharged into gas from the gas vent of valve board assembly
The exhaust chamber intramedullary expansion of cylinder cap simultaneously flow to air exit discharge along exhaust chamber.
Partition is equipped in exhaust chamber of the present invention, partition is equipped with throttle orifice, and refrigerant is only capable of passing through from throttle orifice.
The area of throttle orifice of the present invention is 2 ~ 6mm2。
Sealing surface bottom surface of the present invention and the bottom surface of circular bar are equipped with the sealing strip of a circle outwardly convex, the sealing
The bottom surface of muscle is equipped with the sealing strip connecting with sealing surface and circular bar.
The side wall surface of lid is arranged in air exit of the present invention.
Several reinforcing ribs are equipped in annular channel of the present invention.
The present invention has the advantage that 1 compared with prior art, increases exhaust chamber expands air-flow and along exhaust chamber
It is flowed from import to export direction, reduces compressor air-discharging pulsation, achieved the effect that reduce noise, reduce vibration；2, pass through
Throttle orifice is set in exhaust chamber and further reduces compressor air-discharging pulsation, to further increase noise reduction effect；3, it arranges
Gas cavity and throttle orifice are arranged in the same part (cylinder head of the present invention), and manufacture craft is with conventional cylinder head using identical
Casting technique realizes noise reduction effect under the premise of not increasing cost of manufacture.

Specific embodiment
Referring to Fig. 1-6, the present embodiment includes lid 1, and crankshaft hole is equipped among lid 1, and 1 bottom periphery of lid is equipped with sealing
Face is located at the circular bar 3 being equipped at crankshaft hole towards bottom surface on the inside of lid 1, and a circle sealing is formed between circular bar 3 and lid 1
Exhaust chamber 2, a sealing bar 7 is equipped in exhaust chamber 2,7 one end of sealing bar connects 1 side wall of lid, other end connection ring
Shape muscle 3 separates exhaust chamber 2, and 7 side of sealing bar is equipped with the air exit 5 being connected to exhaust chamber 2,7 other side of sealing bar
2 face valve board assembly of exhaust chamber gas vent, refrigerant is discharged into the exhaust of cylinder head from the gas vent of valve board assembly
2 intramedullary expansion of cavity simultaneously flow to the discharge of air exit 5 along exhaust chamber 2.
1 inside of lid described in the present embodiment is equipped with the settable one or more of throttle orifice 4(on annular channel), refrigerant
It is only capable of passing through from throttle orifice 4, exhaust chamber 2 is throttled hole and is divided into level-one exhaust chamber 2a and secondary exhaust cavity 2b(can also
Multiple throttle orifices are set and form multistage exhaust chamber).
The area of throttle orifice 4 described in the present embodiment is 2 ~ 6mm2(the present embodiment is specifically 4mm2).
Sealing surface bottom surface and the bottom surface of circular bar 3 described in the present embodiment are equipped with the sealing strip 6 of a circle outwardly convex, described
