Claims9
A solenoid valve for a coolant circuit, comprising:
- a valve body with an inlet and at least a pair of coolant outlets, each said outlet formed by a capillary tube;
- a valve member in said valve body displaceable between two positions corresponding to two switching positions of the solenoid valve;
- the dimensions of each said capillary tube are sized such that when coolant passes through the valve, the pressure drop between a beginning and an end of each said capillary tube is a multiple of the pressure drop between said valve body inlet and the beginning of said capillary tube;
- a longitudinal coil for generating a magnetic field in the longitudinal direction in said valve body for shifting said valve body between said two switching positions;
- said valve body arranged outside said longitudinal coil;
- a housing having opposite end walls, each said end wall including a cutout and said valve body mounted therein;
- and
- at least one cover section mounted on said housing and closeable over said valve body to retain said valve body in said housing.
