DOUBLE SOLENOID VALVE WITH DETENT MECHANISM

摘要

A detent mechanism that increases a holding force for the valve member having two switch positions when the valve member is in each of the switch positions includes a ring shaped housing groove which is formed on one of an inner periphery of the valve hole and an outer periphery of the valve member and an annular elevated portion which is formed on the other, and a ring shaped detent member housed in the housing groove, the housing groove includes right and left groove side walls which extend in parallel to each other, and a groove bottom wall, the detent member is made of a material having rubber elasticity and includes right and left side walls which face the groove side walls of the housing groove, and a protruding portion which extends from the housing groove, and a locking section which elastically locks the protruding portion of the detent member in the two switch positions is formed on both ends of the elevated portion in the axis direction.

1. A double solenoid valve with a detent mechanism, the double solenoid valve including a valve hole provided in a valve body having a plurality of ports; and a valve member having two switch positions and housed in the valve hole in a manner movable in an axis direction of the valve hole, the valve member being configured to be driven by two pilot electromagnetic valves, wherein
the double solenoid valve comprises the detent mechanism for increasing a holding force when the valve member is in the two switch positions, the detent mechanism includes a ring shaped housing groove which is formed on one of an inner periphery of the valve hole and an outer periphery of the valve member and an annular elevated portion which is formed on the other, and a ring shaped detent member housed in the housing groove, the housing groove includes right and left groove side walls which extend in parallel to each other, and a groove bottom wall which connects inner bottoms of the groove side walls, the detent member is made of a material having rubber elasticity and includes right and left side walls which extend in a radius direction of the detent member and face the groove side walls of the housing groove, and a protruding portion which protrudes from the housing groove, and the elevated portion includes shoulders on both ends in the axis direction and each shoulder forms a locking section which elastically locks the protruding portion of the detent member in the two switch positions.
