Abstract
Bearing equipped mounting members for mounting a rotor within a rotor chamber of a rotary fluid pressure displacement device. The rotor chamber has axially spaced end walls, and a peripheral wall including a pair of diametrically opposed arcuate walls and a pair of circumferentially spaced radially inwardly opening recesses intermediate the arcuate walls. The rotor has a cylindrical surface of a diameter less than the diameter of the arcuate walls to provide greater than normal running clearance therebetween, and the mounting members are disposed within the recesses for running engagement with the rotor.
Claims2
A rotary fluid displacement device comprising a housing defining a rotor chamber having a peripheral wall defining a pair of diametrically opposed arcuate wall surfaces and a pair of circumferentially spaced radially inwardly opening recesses between said arcuate wall surfaces, said recesses each having a radially inwardly facing surface portion and opposite end surfaces angularly displaced from the inwardly facing surface portion thereof and extending generally radially inwardly toward said arcuate surfaces;
- rotor means in said chamber having a cylindrical outer surface, said arcuate wall surfaces having a diameter greater than that of the outer cylindrical wall surface of said rotor means to provide greater than normal running clearance between said arcuate wall surfaces and said rotor means;
- characterized by a pair of mounting members each disposed in a different one of said recesses and each including an elongated body portion of flexible resilient material and a pair of generally radially inwardly projecting bearing elements secured to opposite ends of the body portion;
- one of said portions of each recess and its respective mounting member being longitudinally flat and the other thereof being curved so that each body portion engages its respective radially inwardly facing surface portion intermediate the ends of each thereof;
- said bearing elements comprising triangular blocks having radially inner edges for sliding engagement with circumferentially spaced portions of the cylindrical outer surface of said rotor means;
- said bearing elements being of a material that is compatible with the material of said rotor means, whereby good sliding engagement between said radially inner edges and said rotor means is obtained;
- said bearing elements being yieldingly urged into said sliding engagement with said outer cylindrical surface by engagement of said body portions with said inwardly facing recess surfaces, said bearing elements having flat outer end surfaces arranged for sliding engagement with the end surface of their respective recesses.
