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.

Abstract: A solenoid valve manifold (10) includes a connector member (70) that is formed by integrating a base portion (71) with a first connector portion (80) configured to electrically connect a first conductive member (52) to a circuit board (41) and a second connector portion (90) configured to electrically connect a second conductive member (62) to the circuit board (41). The base portion (71) has a through-hole (72). The base (30) includes two engagement projections (46). The base portion (71) is elastically deformable in a direction intersecting an insertion direction when the two engagement projections (46) are inserted into the through-hole (72). The connector member (70) is configured to be attached to the base (30) when a part of the base portion (71) around the through-hole (72) is engaged with the two engagement projections (46).

Abstract: A valve unit includes a rotary valve having a predetermined clearance between an inner surface of a main body and a valve element. The magnet coupling includes eight outer peripheral magnets and eight inner peripheral magnets having N-poles and S-poles each on an outer or inner peripheral side. The outer peripheral magnets are disposed such that the N-poles and the S-poles are disposed alternately in a circumferential direction and such that a distance between the central axis and an outer peripheral surface of the outer peripheral magnets is between 90% and 100% of a distance between the central axis and an outer surface of the main body closest to the central axis in a direction perpendicular to the central axis. The inner peripheral magnets are disposed opposite to the outer peripheral magnets such that the N-poles and the S-poles are disposed alternately in the circumferential direction.

Abstract: An electromagnetic valve manifold includes an electromagnetic valve including an output port, a manifold base including an output passage, and a spacer arranged between the manifold base and the electromagnetic valve. The spacer includes a spacer block including a shaft hole and a manual shaft accommodated in the shaft hole. The spacer block includes an output connecting passage that is connected to the shaft hole and connects the output passage and the output port to each other. The manual shaft is configured to be manually operated to be switched between a first switching position, in which the manual shaft allows for connection between the output passage and the output port through the output connecting passage, and a second switching position, in which the manual shaft blocks the connection between the output passage and the output port through the output connecting passage.

Abstract: A pulse shot-type flow rate control device including first and second shutoff valves, a tank, a pressure sensor, and a controller is caused to perform two or more processes. In each process, the controller repeats pulse shots of alternately causing the first shutoff valve and the second shutoff valve to open and close, changes a way of the pulse shots based on a pressure difference between the pressure after filling and the pressure after discharge, and controls a volume flow rate. In each process, the controller stores, as an optimal filling time, a filling time when the volume flow rate is controlled to a target flow rate, and opens and closes the first shutoff valve by using the optimal filling time in a first pulse shot in the next process.
