Description

Piston-rotating engine

Technical field:

The present invention relates to motor, particularly a kind of piston-rotating engine.

Background technique:

Existing motor mostly is reciprocating piston type greatly, but there are many reciprocating mass problems in this motor, the power that makes this kind motor produce is limited, though and comparatively ripe at present wankel engine has the advantage good than conventional engine, but still exist manufacture difficulty big, low speed and fuel economy are relatively poor, use not extensive.

Summary of the invention:

The objective of the invention is to overcome above-mentioned shortcoming and provide that a kind of volume is little, in light weight, power is big, the piston-rotating engine of incendivity gasoline, diesel oil, gaseous fuel.

Formation of the present invention: by body, support, main shaft, piston, cover, suction valve, the oil head, outlet valve, cam mechanism, sealing gasket and check device are formed, body is cylindrical, piston I and Upper shaft sleeve are connected as a single entity, piston I I and Intermediate shaft sleeve are connected as a single entity, piston I II and Lower shaft sleeve are connected as a single entity, on the endoporus main shaft of body, pass through Lower shaft sleeve, Intermediate shaft sleeve and Upper shaft sleeve are installed piston I II successively, piston I I and piston I, the exterior arc surface of each piston cooperates with the body endoporus, cover and back cover before install the front and back of body, the left bottom of body and upper right are provided with suction valve and oily head, preceding cover lower left quarter and back cover upper right quarter are equipped with outlet valve, the right and left horizontal position upper shed at body, be provided with two cam mechanisms, piston I in the outside of opening, piston I I and piston I II are divided into the body endoporus air chamber of three variable volume.

Piston I, piston I I and piston I II radially, off-centeredly be axially arranged with seal groove, between piston and preceding cover and the back cover sealing gasket is installed, in Upper shaft sleeve, Intermediate shaft sleeve and the Lower shaft sleeve of piston I, piston I I and piston I II check device is set respectively.

Compared with the prior art, piston-rotating engine of the present invention, reject crankshaft ﹠ connecting, volume is little, in light weight, power is big, incendivity gasoline, diesel oil, gaseous fuel.
