Abstract

To obtain a manifold type solenoid valve assembly in which an solenoid valve which is equipped with an output port and an solenoid valve which is equipped with no output port are mixed and mounted on a common manifold base. On a valve mounting part of the manifold base which has a plurality of the valve mounting parts of the same type, a first solenoid valve which is equipped with an output port for external piping connection is mounted and a second solenoid valve which is equipped with no output port is indirectly mounted through an intermediate block which is indirectly equipped with an output port for the second solenoid valve.

Claims

a manifold base which has a plurality of valve mounting parts for mounting a solenoid valve;

a first solenoid valve which is directly equipped with an output port for external piping connection;

a second solenoid valve which is not directly equipped with an output port; and

an intermediate block which is indirectly equipped with the output port of the second solenoid valve;

the first solenoid valve being directly mounted on one of the plurality of valve mounting parts and the second solenoid valve being indirectly mounted on another one of the plurality of valve mounting parts through the intermediate block;

wherein

the manifold base has common fluid flow paths for supply and discharge which pass through the manifold base in an axis-line direction, and branched holes for supply and discharge which branch from the fluid flow paths and open on each valve mounting part, the plurality of the valve mounting parts having the same structure as each other in an arrangement of the branched holes and in a structure for mounting the first solenoid valve and the intermediate block; and

the first solenoid valve and the intermediate block have communication holes for supply and discharge which communicate with the branched holes through bonding surfaces against the plurality of valve mounting parts, each bonding surface having a same structure in an arrangement of the communication holes and a mounting structure against the valve mounting parts, thereby making the first solenoid valve and the intermediate block selectively mountable on any valve mounting surface of the manifold base.
