Thermostatic valve controlling oil flow to hydrodynamic coupling - has secondary body moving between two stops and with edge spring-loaded in closure direction

摘要

The thermostatic valve is used to control an oil inflow to a hydrodynamic blower coupling for an engine. A hollow cylindrical, spring-loaded closure member (6) with a face-side seat (7) opposite a closure spring (10) is located in a housing part. The closure member (6) has an axially movable, secondary hollow cylindrical closure body (11) between two stops (12, 13). The second closure unit is spring-loaded (25) in the closure direction. A closure seat (19) on the port (18), which works in conjunction with a valve body (20) operated by a thermostat.
