Abstract

The invention discloses a surface-contact boundary-variable fluid mechanism, comprising an air cylinder, a shaft, an isolator and an internal contact surface structural body, wherein the shaft is arranged in the air cylinder and is provided with a chute, the isolator is arranged in the chute, the internal contact surface structural body is arranged in the air cylinder, and the isolator is hinged with the internal contact surface structural body. The surface-contact boundary-variable fluid mechanism provided by the invention increases a contact area between the isolator and the shaft or the inner wall of the air cylinder, which facilitates lubrication and sealing and enables the life of the fluid mechanism to be prolonged.

Description

technical field [0001] The invention relates to the field of thermal energy and power, in particular to a surface-contact variable boundary fluid mechanism. Background technique [0002] The fluid mechanism of variable boundary is almost all line contact, lubrication and sealing are very difficult, and the life is very short, so it is necessary to invent a fluid mechanism with a large contact area. Contents of the invention [0003] In order to solve the problems of the technologies described above, the technical scheme proposed by the present invention is as follows: [0004] Scheme 1: A surface contact variable fluid mechanism, including a cylinder, a shaft, an isolator and an inner contact surface structure, the shaft is set in the cylinder, a chute is set on the shaft, and the isolator is set In the chute, the inner contact structure is arranged in the cylinder, and the isolation body is hinged to the inner contact structure. [0005] Solution 2: On the basis of solu...
