Embodiment 1

[0049] Such as figure 1 The air distribution mechanism of the reciprocating body shown, the gas distribution mechanism of the reciprocating body includes a reciprocating body 1, a swing rod 3 and a valve 4, a valve seat 5 is set on the reciprocating body 1, and the distribution The air valve 4 is arranged on the air distribution seat opening 5 , and the air distribution valve 4 cooperates with the air distribution seat opening 5 . The gas distribution mechanism of the reciprocating body further includes a connecting rod 2, one end of the connecting rod 2 is rotatably connected to the reciprocating body 1, and the other end of the connecting rod 2 is rotatably connected to one end of the swing rod 3, The other end of the swing rod 3 is rotatably connected with the machine body 6 . The swing rod (3) swings under the action of the reciprocating body (1). The valve valve 4 is acted by the swing rod 3 to open or close the valve seat port 5 according to the timing relationship. ...

Embodiment 2

[0053] Such as figure 2 The difference between the shown reciprocating body gas distribution mechanism and Embodiment 1 is that a guide sliding structure 11 is provided between the valve 4 and the swing rod 3 . The function of the guide sliding structure 11 is to reduce the lateral displacement during the opening and closing process of the valve 4, so that the opening and closing process is more stable and reliable.

Embodiment 3

[0055] Such as image 3 The difference between the shown reciprocating body gas distribution mechanism and Embodiment 1 is that a slideway 101 is provided on the reciprocating body 1 to replace the connecting rod 2 in Embodiment 1. One end of the swing rod 3 is slidingly matched with the slideway 101 , and the other end of the swing rod 3 is connected to the machine body 6 in rotation.

Abstract

The invention discloses a valve actuating mechanism for a reciprocating motion body, which comprises the reciprocating motion body (1), an oscillating bar (3), an actuating valve (4) and a cam (7), wherein the oscillating bar (3) is subjected to the effect of the reciprocating motion body (1) to oscillate, and the actuating valve (4) is subjected to the effect of the oscillating bar (3) or the cam (7) to open or close the actuating valve (4) according to the correct time relation. The technical scheme that valve actuating can be performed on the reciprocating motion body accurately and reliably is provided.

Description

technical field [0001] The invention relates to the field of gas compression, in particular to a gas distribution mechanism. Background technique [0002] Generally speaking, whether it is an engine or a gas compressor, the valve valve is set on a fixed part, such as a cylinder head. However, with the emergence of engines and gas compressors with new structures, in some structures, the valve valve needs to be arranged on the moving parts, for example, the valve valve needs to be arranged on the moving piston or on the cylinder head of the sliding cylinder. wait. In the structure where the gas distribution valve is set on the moving parts, the control of the gas distribution valve is relatively difficult, so it is currently set as a free check valve, which seriously affects the accuracy of gas distribution, so it is necessary to invent a device that can A new type of gas distribution mechanism that precisely distributes gas on moving parts (that is, reciprocating bodies). ...
