ABSTRACT:
This invention relates to a water temperature control device for a cooling system having a reduced number of parts. The water temperature control device circulates cooling water to a water pump through either a radiator or a bypass line depending on the temperature of the cooling water from the water jacket of automobile engine. The water temperature control device provides an improved thermostat seal and prevents piston release of a pellet assembly. The invention comprises a water temperature control device having a case main body formed with a cooling water inlet, a cooling water outlet and a bypass outlet. A valve means is elastically mounted by a spring supported to a frame within the interior of the case main body. A dome type bridge, which holds a front end of the piston of the thermostat, is formed at the interior of the water cooling outlet of the case main body. The front end portion is passed through a pierced hole at the bridge top portion. A calking portion is attached to the front end portion of the piston to prevent release from the dome type bridge during thermostat operation.
