Thermostat valve with temperature responsive thermo-element
A thermostat valve has a cylindrical valve housing formed as a single integrated unit out of synthetic resin material, having an annular body and a frame attached to one end of the annular body by a plurality of legs, a disk-shaped valve stem disposed in another end of the valve housing and movable along an axial direction, a spring seat that holds an opposite end of spring means away from the valve stem and locked and held in place by hooks at tips of locking arms extending from the valve housing, and a thermo-element fixedly mounted to an element guide provided in the frame of the valve housing that moves the valve stem in a valve opening direction in response to fluid temperature. An annular step having a top portion of predetermined width is formed adjacent to the rim of the opening in the one end of the valve housing.
Provided is a coolant passage device configured so that, even if coolant containing bubbles flows into the coolant passage device, the generation of flow noise of the coolant in a heater core can be prevented. A coolant passage device 3 is provided with: coolant intake pipes 11, 12 for taking in coolant flowing from an engine; a delivery pipe 17 leading to a radiator and in communication with the coolant intake pipes; and a delivery pipe 18 leading to a heater core, the delivery pipe 18 being branched from a center passage 16 which connects the coolant intake pipes and the delivery pipe leading to the radiator. In a state in which the coolant passage device 3 is mounted to the engine, a branch opening 18a connecting to the delivery pipe 18 leading to the heater core is open to the upper part inside the center passage 16, and a wall surface 21 hanging down into the center passage 16 is formed at the branch opening 18a so as to surround the branch opening. The wall surface 21 prevents bubbles contained in the coolant from entering the branch opening 18a.
