Abstract
There is disclosed a rotary pump or engine or compressor or expander comprising a spherical cavity divided by a pivotable disc into two sections. First and second wedges are pivotally connected at opposed disc surfaces. One wedge may be driven causing the disc to pivot and rotate the second wedge covering and uncovering suitably positioned inlet and outlet ports for transferring fluid. Novel constructions to simplify manufacturing and improve sealing are described. Other features include a transparent housing part, altering the angle between input and output shafts to vary the displacement and output, and a combined compressor-expander interconnected by a Cardan joint to reduce vibration.
Claims8
A combined device comprising first and second spherical positive displacement devices;
- each of said devices comprising a housing having a cavity therein shaped to form the major portion of a sphere, a disc having a circular periphery and fitted within the cavity for pivotal movement therein and dividing the cavity into first and second sections, first and second wedge-like members, said first wedge member being pivotally connected at one side of the disc and lying within the first cavity section, the second wedge member being pivotally connected at the opposite disc side and lying within the second cavity section, fluid inlet and outlet means coupled to the cavity, the pivotal axes of the first and second wedge members being orthogonal to one another and extending in the same plane and intersecting at the sphere center, and means for journalling for rotation both the first and second wedge members in the housing;
- said first device having one output shaft and the second device having two output shafts with one of the latter connected to the output shaft of the first device;
- a heat exchanger connecting together the respective outlet and inlet means of the first and second devices.
