Problems solved by technology
However, due to the existence of the piston ring (the purpose is to prevent the high and low pressure formed at both ends of the piston from leaking from the gap between the piston and the cylinder), the distance between the piston ring closest to the top of the piston and the top of the piston, and the piston The product of the cross-sectional area of the gap between the cylinder and the inner wall of the cylinder forms a clearance volume, commonly known as "clearance", which has become one of the three major "clearance" problems of existing piston reciprocating compressors , has not been properly resolved

Embodiment Construction
[0013] For an overview of the structural principle of a crankshaft-driven compressor's "no backlash" design, see figure 1 hint.
[0014] 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 .
[0015] 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 cylinder 6 . ...

A totally clearance-free structural form of a piston reciprocating compressor is achieved based on thorough improvement in the aspects of clearance elimination. The totally clearance-free structural form of the piston reciprocating compressor is characterized in that a a cone-shaped air suction valve block (4) for controlling opening and closing of an air suction hole (P) is arranged on the outer side of the top of a piston (5) in a matched mode ; b a piston ring (K) with the V-shaped section is arranged at the position flushed to the outer side and the top of the piston (5) at least; and c the piston (5) can abut against a vent valve piece (3) to rush out of a cylinder (6) in the venting running process, and accordingly a totally clearance-free contact state without geometric space is formed among the piston (5), the vent valve piece (3), the cone-shaped air suction valve block (4) and the cylinder (6) finally. Traditional piston reciprocating compressors which have the largest yield and sales volume in the world are enabled to appear with brand new features, and by means of the characteristics, conditions are created for greatly improving venting efficiency (the actual venting volume is extremely close to 100%) of the compressor type or / and working compression ratio.
Description
technology field. [0001] The invention relates to the structural technology of a piston reciprocating compressor, especially the "no clearance" structural technology. 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] ZL200410030658.3 proposes a "no clearance" structure of a piston reciprocating compressor from...
