Patent FR-2511119-A1 (FR)
Inventor: HERZOG KURT
IPC: F04B49/10
Filed: 1982-08-05
Abstract: A device for feeding an antifreeze agent with a pump into a compressed-air system is proposed. The pump is subjected to the varying pressure of a pressure regulator in the direction of the delivery stroke of its pump plunger (12) and is automatically actuated by the pressure change. A thermostat (19) is provided to automatically switch the pump on in winter and automatically switch it off in summer. The thermostat (19) is preferably arranged coaxially to the pump plunger (12). In this way, it is not left to the driver to estimate the weather situation; during frost the pump switches on automatically and in warm weather it switches off automatically. The pump is advantageously used in compressed-air systems of motor vehicles.
