Embodiment 1

[0035] figure 1 It is a schematic diagram of the first embodiment of the piston of the crank-slider mechanism of the single-cylinder engine of the present invention.

[0036] Such as figure 1 As shown, the piston of this embodiment includes a crown 1 , a piston seat 2 and a piston stopper 3 . Wherein, the crown 1 is arranged at one end of the piston seat 2 . The crown 1 and the piston seat 2 can be integrally formed, or fixedly connected as a whole by means of riveting or screwing. In this embodiment, the crown 1 and the piston seat 2 are integrally formed as an example for illustration.

[0037] The piston seat 2 is provided with a circular slider accommodation hole 2-2, and the piston stopper 3 is detachably assembled on the edge of the end surface of the circular slider accommodation hole 2-2 and passes through the piston seat 2 the waist area. For example, in this embodiment, the piston stopper 3 is fixedly connected to the piston seat 2 through a connecting piece 4 ....

Embodiment 2

[0077] In this embodiment, the shape of the piston stopper 3 is along the figure 2 The arc baffles on the partial periphery of the circular slider accommodation hole 2-2 shown in . There are circular through holes at both ends of the arc-shaped baffle, and an outer stop (not marked) may also be provided on the side of the arc-shaped baffle facing the piston seat 2 .

[0078] The arc-shaped baffle can be assembled on the piston seat 2 of the piston in the same manner as in the above-mentioned embodiment 1.

[0079] The difference is that there are two arc-shaped baffles around each end surface of the circular slider accommodation hole 2-2 of the piston seat 2, which are symmetrically installed on the piston seat 2 to strengthen the Describe the strength of the waist of the piston seat 2.

[0080] On each arc-shaped blocking piece on the periphery of any end surface of the said circular slider accommodating hole 2-2, the same tooth segment as the inner tooth segment 2-7 descr...

Embodiment 3

[0084] In this embodiment, the piston stoppers are also arc-shaped stoppers, and circular through holes are respectively arranged at both ends of each arc-shaped stopper. figure 2 Two arc-shaped baffles are respectively installed on the periphery of each end surface of the circular slider accommodating hole 2-2 of the piston seat 2 shown. On each arc-shaped blocking piece on the periphery of any end face of the said circular slider accommodating hole 2-2, the same tooth segment as the internal tooth segment 2-7 described in the above-mentioned embodiment 1 (the exceptions). Of course, internal tooth segments may also be provided on all the arc-shaped blocking pieces on the periphery of the two end surfaces of the accommodating hole 2-2 of the circular slider. All the features of the internal tooth segment in this embodiment can be the same as those in Embodiment 1, and will not be repeated here.

[0085] The difference from the second embodiment is that when the arc-shaped ...

Abstract

The invention discloses a piston of a circular slider-crank mechanism of a single cylinder engine, comprising a piston seat and a crown arranged at the end of the piston seat, wherein, a circular slider containing hole is arranged on the piston seat. The piston is characterized in that piston separation blades are arranged on the end face edges of the circular slider containing hole and in the zone passing through the waist of the piston seat and are assembled on the piston seat in a demountable way; internal teeth segments are arranged on the piston separation blades on at least one end faceedge of the circular slider containing hole and in the zone passing through the waist of the piston seat. Being used, the piston of the invention can ensure smooth conversion from reciprocating motion to rotary motion and increase the strength of the waist of the piston seat. The invention also provides an internal combustion engine and a compressor.

Description

technical field [0001] The invention relates to a piston, in particular to a piston of a crank circular slider mechanism of a single-cylinder engine. The invention also relates to an internal combustion engine and a compressor. Background technique [0002] In a traditional internal combustion engine or compressor, the conversion between the reciprocating motion of the piston and the rotational motion of the crankshaft is achieved by a crank-connecting rod mechanism. Specifically, in the internal combustion engine, the reciprocating motion of the piston is converted into the rotary motion of the crankshaft through the connecting rod and the crank; in the compressor, the rotary motion of the crank is converted into the reciprocating motion of the piston through the crankshaft and the connecting rod. However, in the above-mentioned crank-link mechanism, due to the existence of the connecting rod, the internal-combustion engine or compressor of the crank-link mechanism has def...
