Title:
SLIDING VANE STRUCTURE, PUMP ASSEMBLY, AND COMPRESSOR
Document Type and Number:
WIPO Patent Application WO/2020/098037
Kind Code:
A1
Abstract:
A sliding vane structure, a pump assembly, and a compressor. The sliding vane structure comprises: a hinge connection sliding vane (10), a first end of the hinge connection sliding vane (10) being hinge-connected to a roller (40), a middle portion of the hinge connection sliding vane (10) having an accommodation cavity (11), and a vent hole (12) communicating with the accommodation cavity (11) being provided on the hinge connection sliding vane (10); and a variable-volume sliding vane assembly (20), the variable-volume sliding vane assembly (20) being movably provided in the accommodation cavity (11), and a refrigerant being introduced into the accommodation cavity (11) via the vent hole (12), such that the variable-volume sliding vane assembly (20) can be in an operation position in which the variable-volume sliding vane assembly (20) is connected to the roller (40), or a dismount position in which the variable-volume sliding vane assembly (20) is separated from the roller (40). In operation, the sliding vane having the above structure reduces a contact area between the variable-volume sliding vane assembly (20) and the roller (40), thereby reducing noise generated by the variable-volume sliding vane assembly (20), and improving the practicability and reliability of a compressor having the sliding vane structure.
