Summary of the invention
The objective of the invention is to overcome the deficiency of existing technology, a kind of cylinder body structure of compressor is provided; This housing structure design science is reasonable, and pressurized gas are cushioned effectively, can reduce gas significantly, reduces the compressor overall noise, and can keep good dynamic balancing.
The present invention solves its technical problem and realizes through following technological scheme:
A kind of cylinder body structure of compressor; Be shaped on connecting base, crankshaft hole and one-level high-pressure buffer chamber, secondary high-pressure buffer chamber on the top of cylinder block base respectively, be shaped on piston hole on the end face of connecting base, this connecting base installs through valve plate and cylinder cap are coaxial; Be fixed with air suction silencer on the cylinder cap, wherein
(1). be shaped on the through hole that is connected with one-level high-pressure buffer chamber and the secondary hyperbaric chamber pore that is connected with secondary high-pressure buffer chamber respectively at the connecting base end face, the through hole in one-level high-pressure buffer chamber is communicated with the secondary hyperbaric chamber pore in secondary high-pressure buffer chamber through made groove on the connecting base end face;
(2). on valve plate, be shaped on one-level hyperbaric chamber pore corresponding with the made through hole in one-level high-pressure buffer chamber and that be communicated with; On valve plate, be shaped on suction port and exhaust port corresponding with piston hole and that be communicated with, suction port is connected with baffler inlet hole on the air suction silencer;
(3). at the suction port top cover labyrinth one suction port valve block is housed, one exhaust port valve block is housed at the exhaust port top cover labyrinth.
And said one-level high-pressure buffer chamber and secondary high-pressure buffer chamber are prepared in the both sides of connecting base.
Advantage of the present invention and beneficial effect are:
1. be shaped on one-level high-pressure buffer chamber and secondary high-pressure buffer chamber on the cylinder block base of the connecting base left and right sides of this cylinder body structure of compressor respectively; Be shaped on through hole that is communicated with one-level high-pressure buffer chamber and the secondary hyperbaric chamber pore that is communicated with secondary high-pressure buffer chamber on the connecting base end face respectively; Be shaped on groove on the connection seat board face, this groove one end is communicated with through hole, and the other end is communicated with secondary hyperbaric chamber pore, and the setting in this kind high-pressure buffer chamber can make pressurized gas reduce flow velocity effectively, reduces the pulsation of air-flow.
2. be shaped on the valve plate of this cylinder body structure of compressor and corresponding suction port of piston hole and exhaust port; Cylinder body one side of suction port is fixed with suction valve chip; Cylinder cap one side of exhaust port is fixed with exhaust valve plate; Also be shaped on the valve plate and the corresponding one-level hyperbaric chamber of the through hole of connecting base pore, the setting of this valve plate can effectively reduce the compressor overall noise with pressurized gas water conservancy diversion stably.
3. scientific structure design of the present invention is reasonable, and pressurized gas are cushioned in this structure effectively, can reduce gas significantly, reduces the compressor overall noise, is a kind ofly can keep good dynamically balanced cylinder body structure of compressor.

Embodiment
Through specific embodiment the present invention is made further detailed description below, following examples are descriptive, are not determinate, can not limit protection scope of the present invention with this.
A kind of cylinder body structure of compressor; Be shaped on connecting base 6, crankshaft hole 13 and one-level high-pressure buffer chamber 1, secondary high-pressure buffer chamber 5 on the top of cylinder block base 4 respectively, be shaped on erection column (not having label) respectively for four jiaos at the lower bottom part of cylinder block base, crankshaft hole extends built in the upper middle position of cylinder block base and to lower bottom part; The both sides of connecting base are provided with above-mentioned two high-pressure buffer chambeies respectively; Be shaped on piston hole 11 on the end face of connecting base, this connecting base is fixed with air suction silencer 3 through valve plate 7 and cylinder cap 2 coaxial installing on the cylinder cap; This air suction silencer side is shaped on baffler inlet hole 8, and cylinder cap, valve plate install with connecting base through screw (among the figure not label) mutually.
