A power feeder for solenoid valves has a printed wiring board carrying a printed feeder circuitry firmly supported on a manifold base. Thus, electrical connection between the solenoid valves and printed wiring board is accomplished simultaneously with the fastening of the solenoid valves to the manifold base. U-shaped brackets having a width corresponding to the width of each solenoid valve are attached to rails provided on one side of the manifold base by fitting engaging shoes provided on one side wall of the brackets over the rails. The printed wiring board is placed on the side walls of the brackets, while the feeding terminal of a terminal box at one end of the connected brackets is connected to the receiving terminal of the printed wiring board by means of a cable connector passed through the brackets. Feeding terminals corresponding to the receiving terminals of the solenoid valves are provided on the printed wiring board so that the feeding terminals on the printed wiring board are directly connected to the receiving terminals of the solenoid valves as the solenoid valves are mounted on the manifold base. This arrangement provides firm support to the printed wiring board, assures easy and sure solenoid valve mounting and feeder terminal connection. Also, the printed wiring board is covered with the brackets and base plates that afford adequate protection from the workshop environment that might be unfavorable.

Power feeder for solenoid valves

In a change-over valve, a valve member consists of a poppet type closure member. A pair of supporting rods are connected to the opposite end portions of the closure member. Guide members made of synthetic resin are connected to the opposite end portions of the supporting rods in order to guide the valve member upon changing over in the directions of fluid flow passages. The guide members prevent the closure member of the valve member from inclined and unstable seating against the valve seats.
