  • Publication number: 20190186303
    Abstract: An oil supply device for a vacuum pump of an internal combustion engine, in particular of a car, including an oil feed line via which the vacuum pump can be supplied with oil for lubricating the vacuum pump. The oil feed line includes a valve connected to the oil feed line in an oil-conducting manner, which valve has a piston that is accommodated in a valve interior of the valve and can move at least between a supply position in which it allows a supply of oil to the vacuum pump and a blocking position in which it prevents the supply of oil to the vacuum pump, and has a spring element, by means of which a spring force that holds the piston in the blocking position can be applied to the piston when the internal combustion engine is at rest.

  • Patent number: 7444962
    Abstract: In a coolant circuit for an internal combustion engine having two cylinder banks, a radiator for cooling the engine coolant, a pump and a thermostatic valve including a mixing chamber and first and second flow control valves, wherein the pump is connected to the radiator via an intake line for receiving coolant therefrom and supplying it to the cylinder banks which are in communication with the mixing chamber from which a radiator line extends to the radiator for returning heated coolant to the radiator under the control of a flow control valve, or supplying it via a bypass line to the intake line under the control of a bypass valve, a heating circuit is provided extending from one of the cylinder banks via a heater to the pump intake line and a heater control valve is disposed in the heating control circuit so that, upon opening of the heater valve, coolant flows from the other cylinder bank via the mixing chamber to the one cylinder bank and coolant from both cylinder banks jointly flows through the heating

  • Patent number: 6843210
    Abstract: A thermostatic valve for a coolant circuit of an internal combustion engine, with a housing through which the flow is capable of passing and which has a first throughflow orifice for connection to a first coolant line, a second throughflow orifice for connection to a second coolant line, and a third throughflow orifice for connection to a third coolant line, and with a closure member which is mounted in the housing and which can be adjusted by an actuating unit, the closure member having a first shut-off element for shutting off the first throughflow orifice and a second shut-off element, coupled to the first shut-off element, for shutting off the second throughflow orifice.
