摘要： The cooling water temperature control device includes a thermo valve 2 that opens a main flow passage R1 when the temperature of a sensed region R1a in the main flow passage R1 reaches or exceeds an operating temperature set in advance, a sub-valve 3 that opens and closes a sub-flow passage R2 bypassing the thermo valve 2, and a control unit 6 that opens the sub-valve 3 when the temperature of the cooling water on an upstream side of the thermo valve 2 is a predetermined temperature. One end on the upstream side of the sub-flow passage R2 is connected to the sensed region R1a in the main flow passage R1 or to a downstream side of the sensed region R1a, and the operating temperature of the thermo valve 2 is set to be equal to or lower than the predetermined temperature.

摘要： A thermostat device provided with a cylindrical boss protruding into a flow of fluid flowing in from a fluid inlet inside a device housing from a direction obstructing the flow of fluid, wherein a rectifying wall in the shape of a thin plate that protrudes toward an upstream side of the flow of fluid from the boss is provided as a rectifying means. The rectifying wall is formed in the shape of a plate that gradually increases in thickness from the fluid inlet side toward the boss. The leading edge along a direction of the flow of fluid is formed to have a tapered shape inclined from the tip of the boss toward the base of the boss. A side of the boss opposite the side facing the fluid inlet is provided with a rib.

摘要： Provided is a fluid control valve assembly which reduces pressure loss as much as possible in a fluid passage line including a fluid control valve, thereby mini-minimizing the pressure for a fluid to pass therethrough and thus ensuring a required amount of flow without upsizing the overall assembly. The fluid control valve assembly is adapted such that an upstream pipe (17) forming an upstream fluid passageway and tilted at a predetermined angle relative to a valve axis (L) is provided to face an upstream chamber (11). The upstream chamber is formed upstream of a valve portion (12) which has a valve seat (13) and a valve body (14) in a valve housing (10) and which can open and close the fluid passageway. The wall surface of the upstream chamber is integrated with a swelling (20), which is projected in the chamber to thereby rectify and guide the fluid flowing therein through the upstream pipe so that the fluid smoothly flows to the valve portion.

摘要： A thermo valve has a valve chamber disposed inside a housing and open to a first flow path through an opening. Second and third flow paths open into the valve chamber. A thermo-element that can move back and forth axially inside the valve chamber in response to fluid temperature opens and closes the second and third flow paths and is biased in a direction that blocks the flow paths by a coil spring. A valve element that is a bypass valve that opens and closes an opening that connects the first and third flow paths inside the valve chamber and communicates the first and third flow paths is disposed in the opening. The coil spring is also used to bias the valve element in a direction that blocks the flow paths.
