Abstract
Methods and systems are provided for a valve for controlling the flow of a fluid medium in a coolant circuit of an internal combustion engine. The valve is configured to react to the temperature of the coolant via an expansion element and to the charge pressure in the intake tract via a pressure-sensitive actuator.
Claims20
A system, comprising:
- a valve configured to adjust a flow of a fluid in a coolant circuit of an engine, the valve comprising an expansion element coupled to a transmission pin to adjust the flow of the fluid through the valve based on a temperature of the fluid, wherein the transmission pin is further coupled to a pressure-regulated actuator, the transmission pin actuated based on a charge pressure at the pressure-regulated actuator.
A valve for a coolant circuit, comprising:
- a first connection for admitting fluid to the valve;
- a second connection for expelling fluid from the valve to a heat exchanger;
- a third connection for expelling fluid from the valve to a bypass;
- a transmission pin configured to adjust an opening size of the second connection and the third connection;
- an expansion element coupled to the transmission pin and configured to adjust a position of the transmission pin in response to a fluid temperature;
- and
- an actuator coupled to the transmission pin and configured to adjust the position of the transmission pin in response to a charge pressure.

A vehicle, comprising:
- an engine;
- a compressor;
- a coolant circuit fluidly coupled to the engine, the coolant circuit comprising a heat exchanger and a bypass;
- and
- a valve arranged in the coolant circuit, the valve comprising a first connection configured to receive coolant from the cooling circuit downstream of the engine, a second connection configured to expel coolant from the valve to the heat exchanger, and a third connection configured to expel coolant from the valve to the bypass;
- the valve further comprising a transmission pin coupled to an expansion element and an actuator, wherein the expansion element is configured to adjust a position of the transmission pin in response to a coolant temperature and the actuator is configured to adjust the position of the transmission pin in response to a charge pressure.
