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

[0022] figure 1 The structural overview of a crankshaft-driven piston reciprocating compressor "no backlash" is shown.

[0023] figure 2 It shows the situation that the piston 5 carries the piston ring K together against the exhaust valve plate 3 and travels outside the hole of the cylinder 6 during the forward compression and exhaust stroke. Obviously:

[0024] A. Before the piston 5 contacts the exhaust valve plate 3, a high-pressure air cushion has been formed in the cylinder 6 between the two to relieve the mutual impact of the piston 5 and the exhaust valve plate 3;

[0025] B. This means that: the piston 5 has squeezed all the compressed high-pressure gas into the high-pressure zone H;

[0026] C. Should ensure in structural design: piston ring K can not all disengage (rush out) the hole of cylinder, otherwise, piston ring K just can not be carried back cylinder 6 again by piston 5. In addition, the part of the stroke in which the piston 5 rushes out of the opening ...

Abstract

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...
