Abstract
An object of the present invention is to improve assembling workability of the flow passage block and the sealability between the manifold solenoid valve and the flow passage block. A flow passage block 61 is mounted on a manifold solenoid valve having valve bases 12 on which solenoid valves 11 are respectively mounted, a block mounting face 60 is formed by the valve bases 12, an output joint 36 protrudes from each valve base, a joint seal member 71 is detachably mounted on the output joint 36, with the flow passage block 61 being mounted on the block mounting face 60, the joint seal member 71 seals between an outer peripheral surface of an output joint 36 and an inner peripheral surface of an connecting hole 64 which communicates with an air passage of the flow passage block 61.
Claims7
A manifold solenoid valve, comprising:
- valve bases on which solenoid valves are respectively mounted;
- output joints which are provided so as to protrude from the respective valve bases, the output joints communicating with output ports of the solenoid valves, and each output joint having an annular engaging protruding part projecting radially from an outer peripheral surface;
- joint seal members mounted on the output joints for outputting air, each joint seal member having an inner peripheral surface and an outer peripheral surface, the inner peripheral surfaces of the joint seal members engaging the outer peripheral surfaces of the output joints;
- wherein an annular recess part is provided on the inner peripheral surface of each joint seal member,
- the annular engaging protruding part of each output joint projecting radially is fitted into the annular recess part of the joint seal member, and
- at least one annular protruding seal part is provided on the outer peripheral surface of the joint seal members, and the one annular protruding seal part is disposed so as to correspond to the annular engaging protruding part of the output joints,
- wherein the annular engaging protruding part projecting radially from the peripheral surface of each output joint has:
- a cylindrical outer surface with a proximal end and a distal end;
- a tapered surface extending from the distal end of the cylindrical outer surface toward a distal end of the output joint;
- and
- a radially directed surface extending radially inwardly from the proximal end of the cylindrical outer surface.
