Abstract
A pump particularly adapted for use in a closed fluid circuit, as within its housing a resiliently compressible chamber in contact with the fluid being conveyed by the pump so that any pressure change within the fluid caused by temperature variations can be volumetrically absorbed by compression or extension of the chamber.
Claims11
A pump used for conveying fluid in a closed fluid circuit, said pump comprising:
- a housing having a plurality of walls;
- and
- a resiliently compressible chamber within said housing and in contact with said fluid circuit;
- whereby any expansion of said fluid is compensated by a corresponding volumetric compression of said chamber.
