Problems solved by technology
[0002] Most of the types of compressors that come out at present are conventional piston compressors driven by the crankshaft, which have the comprehensive characteristics of simple manufacture, long service life, and low requirements on materials, etc. , which is the main reason why it has been enduring since its inception
[0003] Piston reciprocating compressors, like other compressors, are plagued by unsolvable "clearance" problems in structure, so it is always difficult to improve their exhaust efficiency or / and compression ratio

Embodiment Construction
[0021] For an overview of the structural principle of the "no backlash" design of a crankshaft-driven compressor, see the above figure 1 hint.
[0022] When the piston 5 is in the compression stroke, before it comes into contact with the exhaust valve plate 3, a high-pressure air cushion that will relieve the impact of each other has been formed in the cylinder 6 between the two. Once the piston 5 carries the piston ring K and rushes out of the hole of the cylinder 6, the high-pressure gas that has been compressed will be squeezed into the high-pressure area H, and at the same time, together with the piston ring K, it will be in contact with the exhaust valve plate 3 and against the exhaust valve. The valve plates 3 travel together outside the bore of the cylinder 6 .
[0023] figure 2 It illustrates the situation that the above-mentioned piston 5 is carrying the piston ring K together, pushing against the exhaust valve plate 3 and traveling together outside the hole of the...

The invention relates to a design scheme for a clearance-free piston reciprocating compressor, which is realized by improving completely removal of the 'clearance', i.e. by the improvement on the basis of 'clearance-free' technology of ZL2004100030658.3. According to a structure principle, a 'clearance-free' contact status without a geometric space can be formed among a piston (5), a displacing valve (3), a cone-shaped air suction valve block (4), a piston ring (K) and an air cylinder (6) in a moment. Therefore, the most traditional piston reciprocating compressor appears with a brand new type in the world: the actual air displacement of the piston (5) very closely approximates 100 % under any working condition, the compression ratio of the piston can be further improved greatly, a condition for the clearance-free piston reciprocating compressor to replace the traditional piston reciprocating compressor is created, and even a condition for the clearance-free piston reciprocating compressor to possibly replace various different types of compressors applied in other engineering fields is created as 'cost performance' of the clearance-free piston reciprocating compressor is greatly improved.
Description
technology field. [0001] The present invention relates to the technology of piston reciprocating compressor, especially the technology of "no clearance" type. Background technique [0002] Most of the types of compressors that come out at present are conventional piston compressors driven by the crankshaft, which have the comprehensive characteristics of simple manufacture, long service life, and low requirements on materials, etc. , which is the main reason why it has been enduring since its inception. [0003] The piston reciprocating compressor, like other compressors, suffers from the unsolvable "clearance" problem structurally, so it is always difficult to improve its exhaust efficiency or / and compression ratio. ——For example: when the compression ratio is close to "10", its exhaust volume will be reduced to the extent that it loses its working significance. [0004] The "clearance" in the existing piston reciprocating compressor includes: the "clearance" that must ex...
