ABSTRACT:
In a number of patents my former art of control bodies which have centric and eccentric portions are disclosed for the passing and control of flow of fluid into and out of working chambers in fluid handling devices, such as fluid pumps, motors, compressors, transmissions.
The invention discovers, that those control bodies of the former art under certain circumstances tend to rotate slightly by a few degrees under friction in the control mirror and then stick very strongly their seats whereby they lose their ability to adjust themselves axially and for good seal under small friction along the stationary control face of the rotor.
The invention overcomes this problem by providing a retainer on a stationary portion in the device to prevent the control body from any rotation around one of its axes. The smooth operation of the control body is thereby assured and the former sticking and loss of ability to operate perfectly is overcome.
