Embodiment Construction

[0014] Figure 1 highlights the structural overview of the "no backlash" design of a crankshaft driven compressor.

[0015] As shown in Fig. 2, the piston 5, which is doing the compression and exhaust work, squeezes all the compressed high-pressure gas into the high-pressure zone H, and then it continues to rush out of the cylinder 6 against the exhaust valve plate 3, and Enter high pressure zone H. At this time, the geometric space ("clearance") between the piston 5, the conical suction valve block 4 and the exhaust valve plate 3 is not difficult to reach extremely close to "zero", or even equal to "zero". . The stroke of the piston 5 rushing out of the cylinder 6 can usually be controlled at about 1 / 10 of its effective suction stroke length.

[0016] As shown in Figure 3, when the piston 5 retreated into the cylinder 6 completely, the exhaust valve plate 3 positioned by the spring 2 would naturally allow it to be driven by high air pressure to seal the top of the cylinder 6...

Abstract

The invention relates to a designing scheme of a no-gap piston reciprocation compressing engine, which is based on the basic structure of conventional piston reciprocation compressing engine with the most production and sale, characterized in that gasvalve chip (3) driven by piston (5) in discharging process dashes out of cylinder (6) and enter into high pressure region (H), here the no-gap state among piston (5), gasvalve chip (3) and sorption valve block (4) while conical-capping sealing structure is formed by the contacting face between sorption valve block (4) and the outside of piston (5) top. Based on the said characters, there is the condition to widely improve working compressing ratio or discharging efficiency of the compressing engine so that conventional piston reciprocation compressing engine is presented with a brand-new appearance.

Description

Technical field: [0001] The present invention relates to piston compressor technology. Background technique: [0002] Most of the types of compressors that come out at present are conventional piston reciprocating compressors, which have comprehensive characteristics such as simple manufacture, long service life, and low requirements on materials, which cannot be compared with other types of compressors. It is the main reason why it has been enduring since its inception. [0003] However, its disadvantages are as follows: it is difficult to improve its working compression ratio or exhaust efficiency. And one of the main reasons why it is difficult to improve and stagnate is exactly: it is difficult to improve its "volume" efficiency structurally, that is, to reduce the design efficiency of its "clearance" structurally, and the "clearance" mentioned in the title of the present invention No clearance" design is unimaginable. Invention content: [0004] Purpose of the pres...
