Description

Plunger type fluid compression engine
Technical field
The invention belongs to fluid compression apparatus, particularly relate to a kind of plunger type fluid compression engine.
Background technique
Usual compressor is mainly had by structure type: reciprocating-piston (or plunger) formula, rotating vane or Rotary screw etc.. Reciprocating-piston fluid (gas or liquid) compressor is generally by drive shaft (crankshaft or camshaft), piston and cylinder sleeve (or plunger And plunger bushing), flow into check valve, the discharge composition such as check valve.
Reciprocating-piston compressor is usually the linear reciprocating motion that drive shaft rotary motion is converted to piston, to make to press The Fluid pressure for contracting intracavitary increases.Most of compressors complete above-mentioned movement, the design of this structure by means of crankshaft-and-connecting-rod component Deficiency be that crank link mechanism needs space larger in entire circulation.Further, since crankshaft, connecting rod shape are complicated, processing Difficulty is big, causes compressor installation process complicated, equipment investment is big.Existing actuated by cams piston rod construction eliminates crank connecting link Mechanism, simplifies the driving mechanism of device, and structure is relatively easy.But in general actuated by cams piston lever arrangement, because cam rotates Piston (or plunger) is pushed to move in a straight line, piston (or plunger) boom end needs to fit in opposite sliding on cam curved surface, but Cam and piston rod (or plunger) are relative separation structures, i.e. cam not stretchy piston (or plunger) return, therefore need to be furnished with The devices such as reset spring push back piston (or plunger), and piston (or plunger) rod end is made to be bonded cam curved surface always, realize piston The reciprocating motion of (or plunger).
Applicant retrieval patent document include:
A kind of oil-free air compression of symmetrical cam driving is disclosed in the patent document of Publication No. CN103603786A Machine, the mechanism are that cam pushes guide rod promotion piston progress compressed air, return to piston and guide rod by reset spring It is in situ.The above-mentioned prior art uses reset spring, in cylinder compression stroke, in addition to cylinder acting (effectively acting), also needs Compression reseting spring acting (invalid acting), while keeping mechanism more complex using reset spring, occupied space is larger.
Summary of the invention
The purpose of the present invention is to provide a kind of plunger type fluid compression engines, by the way that shaft coupling is arranged in plunger base, partially Heart wheel drives shaft coupling to rotate with it the reciprocating motion for driving plunger to realize in plunger bushing, saves offsetting spring structure, makes structure It is more compact, more set plunger mechanisms can be arranged in the useful space, are saved compression travel and are pushed what reset spring was done Idle work improves efficiency to reduce energy consumption, and can also reduce the frictional force and abrasion of the process of pushing.
