Swing piston power machine

Abstract

The invention discloses a swing piston internal combustion engine structure, and relates to the field of power machines. A swing piston power machine is mainly composed of the components such as an air cylinder, a swing piston, a swinging plate, a main shaft, a swash plate, a spark plug and an intake and exhaust system; the swing piston is mounted in the air cylinder, and is mutually matched with the inner surface of the air cylinder to form four working chambers; along with the swing of the swing piston, the volumes of the working chambers change periodically, and the four strokes of air suction, compression, acting and air exhaust are completed; the swing piston is connected with the main shaft through the swash plate, and mutual conversion between the swing of the piston and the rotation of the main shaft is completed. The swing piston power machine has the advantages of simple and compact structure, large power density, small friction, high operational reliability and efficiency and the like.

Description

technical field [0001] The invention belongs to the field of power machinery, and relates to a design of a power machinery structure, in particular to a design of a swing piston power machinery mechanism. technical background [0002] Due to the widespread use of small aircraft, robots, and portable power supplies, power machinery with compact structure, high power density, high reliability, easy maintenance, and low cost is required as a power source. At present, under the existing technical conditions, the swing piston power machinery It has advantages over power machinery of other structures. [0003] In the existing technology, US Patents US3338137 and US4884532 both adopt a swing piston structure, and the swing piston is slidably connected on the piston pillar, so that the friction between the piston and the cylinder is reduced; especially in US4884532, each swing piston and the cylinder form two A working chamber greatly simplifies the structure, enhances the reliabil...

[0003] In the existing technology, US Patents US3338137 and US4884532 both adopt a swing piston structure, and the swing piston is slidably connected on the piston pillar, so that the friction between the piston and the cylinder is reduced; especially in US4884532, each swing piston and the cylinder form two A working chamber greatly simplifies the structure, enhances the reliability, and provides a guarantee for increasing the power density. However, both schemes use the crankshaft connecting rod structure, which provides a reliable guarantee for the power output, but due to the crankshaft The existence of the box has brought adverse effects on the compactness of the whole machine and the improvement of power density.
