Title: Pressure control for IC engine coolant circuit - has float monitored coolant level in expansion tank and with two-level pressure control
Inventor: GEORGS GEORG DIPL ING
IPC: F01P11/02
Filed: 1992-08-25
Abstract: The coolant circuit for the IC engine (2) has connecting lines (11a,11b) to each side of a main expansion tank (10). The tank is vented by a first pressure control valve (14) into a second expansion tank (16) at atmos. pressure. A second venting valve (18) at higher pressure also vents into the second tank.
