摘要： A coolant passage device 3 includes coolant intake pipes 11 and 12 that take in coolant from an engine, a delivery pipe 17 to a radiator communicating with the coolant intake pipes, and a delivery pipe 18 to the heater core branched from a central passage 16 connecting the coolant intake pipes with the delivery pipe to the radiator. A branch port 18a leading to the delivery pipe 18 to the heater core is opened in an upper portion in the central passage 16 in a state where the coolant passage device 3 is mounted to the engine, and the branch port 18a has a wall surface 21 surrounding the branch port and hanging down into the central passage 16. The wall surface 21 prevents bubbles contained in the coolant from entering the branch port 18a. And the coolant passage device consequently prevents coolant flow noise from occurring.

摘要： Provided is a fluid control valve assembly which reduces pressure loss a fluid passage line including a fluid control valve, thereby mini-minimizing the pressure for a fluid to pass therethrough to ensuring a required amount of flow without upsizing the overall assembly. The fluid control valve assembly includes an upstream pipe forming an upstream fluid passageway tilted at a predetermined angle relative to a valve axis to face an upstream chamber. The upstream chamber is formed upstream of a valve portion which has a valve seat and a valve body in a valve housing and which can open and close the fluid passageway. The wall surface of the upstream chamber is integrated with a swelling, 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 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： A temperature adjustment device is capable of suppressing sleeve enlargement and preventing the rattling thereof with a synthetic resin housing. Flanges are formed on the temperature adjustment member. The sleeve has a groove along the circumferential direction on its outer periphery and a lateral hole opening at one end to the groove and penetrating through the wall thickness of the sleeve. A clip member has an outer fitting portion, elastically deformable and fittable to the groove and has an inward convex portion holding the flange from the distal-end side of the sleeve, by being inserted in the lateral hole. The groove wall has a groove-depth wall at the deepest portion opposite to the groove opening and a distal-proximal-end-side curved portion of the groove-depth wall connected to the distal-proximal-end side of the sleeve. The radius of curvature of the distal-end-side curved portion is larger than that of the proximal-end-side curved portion.
