Abstract: 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.

Abstract: 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.

Abstract: A rotary valve seal member that is held in sliding contact with a valve element that rotates, turns, or slides within a valve housing of a rotary valve and is capable of providing a secure seal as the valve element operates. The seal member has the structure of a three-dimensional ring having a cross-section composed of an oval portion, aligned with a normal line to the outside of the valve element and having a bulge at the end that protrudes and presses against the outer surface of the valve element, and a rectangular portion, into which the oval portion is integrated in a state in which the oval portion is aligned with the normal line to the outside of the valve element, that is retained within an annular groove with the outer side of the rectangular portion in contact with the wall of the annular groove.

Abstract: A thermo-element having incorporated in a case a heat expansion body which expands and contracts according to a change in temperature includes: a piston disposed along the axis direction within the case, protruding outward from the opening on one end side of the case, and advancing and receding as the hear expansion body expands and contracts; a guide member disposed within the case and which slidably holds the piston; and a first valve element fitted to an outside portion of the case, in the side of the case, and opening and closing a fluid flow path. A fit-in section of the first valve element and insertion sections of the guide member inserted within the case are displaced from each other in the axis direction and the radial direction of the case.
