  • Positive displacement hydraulic unit with near-zero side clearance
    Patent number: 6250900
    Abstract: A positive displacement hydraulic unit includes a housing having a chamber formed therein with a circumferential surface bounded by a pair of spaced apart end walls. A rotary element for displacing fluid rotatably mounts in the chamber. A layer of abradable coating material is positioned between an end wall of the chamber and the adjacent side wall of the rotary element so as to provide a near-zero side clearance for the rotary element and thereby high volumetric efficiency for the hydraulic unit.
