STATIC PRESSURE ROTARY CONNECTOR WITH INTEGRAL COMPENSATING ELEMENT

摘要

A rotary connector for fluid transmission between a housing part and a shaft via rings has a bypass provided with a valve which connects the intermediate pressure space with either the leakage space or the main pressure space upon a drop in the main pressure below the pressure in the intermediate pressure space to provide inverse gap control and thereby prevent the sliding ring from pressing mechanically agains the counter-ring and generating sliding friction, heat and wear.
