Abstract: A fluid control device manifold includes a first body, a second body, and a connection part configured to interpose a seal member between the first and second bodies and allow a connecting tool to engage with engagement surfaces of the bodies. When a load is applied to the engagement surfaces to draw the first and second bodies close to each other, the seal member is press-fitted into the bodies. This press-fitted state is held by a clamp. One or both of the first and second bodies are internally provided with a plurality of the engagement surfaces extending in a nearly perpendicular direction to a drawing direction.

Abstract: In a connected-part seal structure configured to couple a first connected part and a second connected part through a seal member, the taper angles of first and second inner pressure-contact tapered parts provided in the seal member are smaller than the taper angles of first and second inner tapered parts provided in the first and second connected parts. Thus, a pressure-contact force of first and second inside tapered pressure-contact allowances are larger as the inside tapered pressure-contact allowances are located closer to base end parts of first and second annular protrusions.

Abstract: A fluid-device connecting structure includes a first fluid device having a first connection part, a second fluid device having a second connection part, an annular seal member to connect the first and second connection parts, and a coupling member to keep the first and second connection parts in a connected state. The coupling member includes a first coupling segment and a second coupling segment, each including at one end a first hinge part or a second hinge part. The first and second connection parts each have a cylindrical outer shape. The first coupling segment has a U-like shape having an opening and surrounds the first and second connection parts over a range more than 180 degrees of an entire circumference of each of the first and second connection parts.

Abstract: The present invention relates to a tube with coupling according to which liquid leakage and the like can be suppressed as much as possible when couplings are connected. A tube with coupling (10) according to the present invention is a tube with coupling (10) obtained by forming a coupling (30) on a leading end portion (22) of a tube (20) through injection molding, and the leading end portion (22) of the tube (20) is arranged at a position set back from a leading end portion (32) of the coupling (30), at least a portion of the leading end portion (22) of the tube (20) being covered by the coupling (30). It is desirable that a flange (36) is provided so as to protrude outward at a position set back from the leading end portion (32) of the coupling (30) and the leading end portion (22) of the tube (20) is arranged at a position set further back from the flange (36).

Abstract: A fluid control valve includes: a resin valve main body including inlet and outlet ports in opposite side surfaces, a valve chamber communicating between the inlet and outlet ports and opening at the upper surface center of the main body, and a valve seat provided in an inner wall of the chamber; a valve element movable into or out of contact with the valve seat; and a valve upper body including a drive part to drive the valve element. An inflow passage is formed like an L shape extending through the inner wall to communicate between the inlet port and the chamber via the valve seat. The inner wall is cylindrical having a thick-wall portion to have a wall thickness thicker on the inlet port side than on the outlet port side. The valve main body is provided, at a center of a lower surface, with a resin injected part.
