Abstract

Attaching/detaching workability of a fitting block to/from an solenoid valve assembly is improved, and a fixing strength of the fitting block to the solenoid valve assembly is enhanced. The fitting block 41 is intended to be detachably mounted to the solenoid valve assembly 12, and the fitting block 41 is provided with port connecting tubes 42 and 43 detachably fitted in output ports A and B, and tube fittings 44 and 45 to which tubes 46 are connected. The fitting block 41 is further provided with an engagement projection 52 which is engaged with a concave portion 51 formed in the solenoid valve assembly 12, and the fitting block 41 is fixed to the solenoid valve assembly 12 via a portion of the engagement projection 52 by a clip 53 engaged with an engagement groove 57 formed in the engagement projection 52.

Claims

1. A solenoid valve manifold comprising:

an approximately quadrangular plate-like solenoid valve assembly in which a supply hole and an exhaust hole are formed so as to penetrate therethrough in a thickness direction and in both surfaces of which abutting surfaces are provided;

a fitting block provided with a port connecting tube detachably fitted in an output port formed so as to be open in a side surface of the solenoid valve assembly, and a tube fitting to which a tube communicating with the output port is connected;

an engagement projection provided to the fitting block, and engaged with a concave portion formed adjacently to the output port in the side surface of the solenoid valve assembly; and

a clip movably mounted to the solenoid valve assembly, and fixing the fitting block via a portion of the engagement projection, the clip including leg portions engaged with respective engagement grooves formed in both surfaces of the engagement projection, and an operating portion linking the leg portions by respective distal portions of the leg portions,

wherein the fitting block is provided with a first port connecting tube fitted in a first output port formed so as to be open in the side surface of the solenoid valve assembly, and a second port connecting tube fitted in a second output port formed in parallel with the first output port, the engagement projection being provided between the first port connecting tube and the second port connecting tube.

2. The solenoid valve manifold according to claim 1, wherein an entirety of each of the engagement grooves is engaged with the clip.

3. The solenoid valve manifold according to claim 1, wherein the clip is provided with a stopper which abuts on a movement regulating portion provided to the solenoid valve assembly when the clip is moved in a direction in which the clip is separate from the engagement grooves.

4. A solenoid valve manifold comprising:

an approximately quadrangular plate-like solenoid valve assembly in which a supply hole and an exhaust hole are formed so as to penetrate therethrough in a thickness direction and in both surfaces of which abutting surfaces are provided;

a fitting block provided with a port connecting tube detachably fitted in an output port formed so as to be open in a side surface of the solenoid valve assembly, and a tube fitting to which a tube communicating with the output port is connected;

an engagement projection provided to the fitting block, and engaged with a concave portion formed adjacently to the output port in the side surface of the solenoid valve assembly; and

a clip movably mounted to the solenoid valve assembly, and fixing the fitting block via a portion of the engagement projection, the clip including leg portions engaged with respective engagement grooves formed in both surfaces of the engagement projection, and an operating portion linking the leg portions by respective distal portions of the leg portions,

wherein a slide plate is mounted on a surface of the solenoid valve assembly so as to be movable between a position of covering the operating portion of the clip and a position of exposing the operating portion to an outside.
