Class Information
Number: 417/219
Name: Pumps > Condition responsive control of drive transmission or pump displacement > Adjustable cam or linkage > Radially adjustable stator
Description: Apparatus wherein the relatively movable pumping member and chamber comprise a rotor and an encompassing movable stator in which movement of the stator causes the pumping member to move radially of the axis of rotation of the rotor resulting in a change in the stroke of the pumping member or a change in displacement of the pump.
