Embodiment Construction

[0030] The first embodiment of the present invention provides a single-acting piston, which can cooperate with a double-acting piston to form a piston group, which is used in a reciprocating piston type internal combustion engine with crank double circular sliders. The double-acting piston can adopt the forms provided by the prior art. For example, Fig. 10 and Fig. 11 of Chinese patent document CN1067741C provide a double-acting piston form. figure 1 , figure 2 That is, respectively, Fig. 10 and Fig. 11 of the double-acting piston provided according to the above-mentioned patent documents. The double-acting piston will be briefly described below.

[0031] From figure 1 , figure 2 It can be seen that the two ends of the double-acting piston are working parts with the same shape and size. In the present invention, the working part is called crown 1; the crown 1 is cylindrical, and its top surface is the piston top. 1-1, the piston top 1-1 is the lower bottom of the combus...

Abstract

The invention discloses a single action piston for a crank round sliding block mechanism; the single action piston comprises a piston seat and a crown part arranged at one end of the piston, wherein the proper part of the piston seat is provided with a balance weight body which can be used for increasing the mass of the single action piston so as to make the mass of the single action piston be matched with another piston that is matched with the single action piston for use; and the position where the balance weight body is arranged can simultaneously make the center of gravity of the single action piston to be arranged at the needed position. Preferentially, the balance weight body of the piston is arranged at the other end of the piston correspondingly to the crown part. As the single action piston for the crank round sliding block mechanism is provided with the balance weight body, the mass of the single action piston can be adjusted by selecting the balance weight body with different weights, and the mass ratio between the balance weight body and the piston assembled with the balance weight body can be ensured to be proper; in addition, the center of gravity of the piston can be arranged at the needed position by selecting the single action position of the balance weight body on the piston seat.

Description

technical field [0001] The invention relates to piston technology, in particular to a single-acting piston used in a crank circular slider mechanism. The present invention also relates to an internal combustion engine and a compressor using the above-mentioned piston set. Background technique [0002] The kinematic mechanism of a traditional engine is a crank linkage mechanism. Under this kind of kinematic mechanism, the reciprocating motion of the piston needs to be transmitted to the crankshaft through the connecting rod connected to it. During the movement, the connecting rod swings back and forth with the movement of the piston, so that the piston is subjected to a periodic change with a higher-order function. lateral force. [0003] Due to the existence of the connecting rod, the internal combustion engine of the crank connecting rod mechanism has disadvantages such as bulky, heavy, and poor balance performance. The characteristic is that the connecting rod is cancel...
