Reciprocating stroke apparatus

Abstract

The invention discloses a reciprocating travel device, comprising a casing, a piston, a temperature control unit and a transmission module. The piston can be flexibly arranged in the casing, thereby, a first chamber and a second chamber are formed on both sides of the piston inside the casing. The first chamber is filled with gas, the transmission module corresponds to the second chamber and is arranged on the other side of the casing; the temperature control unit is used to repetitively heat and cool the gas in the first chamber so as to drive the piston to make reciprocating movements inside the casing, and as a result, the transmission component is facilitated to make reciprocating travel.

Description

technical field [0001] The invention relates to a reciprocating stroke device, in particular to a reciprocating stroke device which utilizes a temperature control unit to repeatedly heat and cool the gas filled in a shell to drive a piston inside the shell to reciprocate. travel device. Background technique [0002] Existing reciprocating stroke devices, such as hydraulic cylinders or pneumatic cylinders, usually must cooperate with driving components such as pumps to achieve predetermined reciprocating stroke actions. In addition, conventional pumps generally need to be connected to a tympanic chamber through a driving motor. The driving motor has a rotating shaft, and the rotating shaft extends into the tympanic chamber to combine with an impeller. In this way, the rotating shaft of the driving motor can be used to actuate the impeller to rotate at a high speed, so as to use the eddy current generated by the impeller to pump liquid or gas, and then drive an actuating rod ...

AI Technical Summary

Problems solved by technology

[0003] Generally speaking, the above-mentioned existing reciprocating stroke device has the following disadvantages, for example: no matter it is a reciprocating stroke device such as a hydraulic cylinder or a pneumatic cylinder, it usually still needs to cooperate with the function of the pump that can pump liquid or gas to achieve a predetermined purpose. reciprocating action

However, the driving motor of the pump tends to generate a lot of noise during operation, which causes the surrounding working environment to be too noisy

Further, since the pump generally must still be equipped with the drive motor, it also has many problems such as relatively large volume and relatively complicated structure.

Overall, the existing reciprocating stroke devices (including components such as pumps) are not suitable for working places where the space is relatively narrow and the noise level is not too large
