PURPOSE:To obtain a long life of the captioned valve while suppressing its contact noise, by setting up a pair of rubber cushion with a specified distance there between along sliding direction of a movable piece and spool, inside a reciprocating drive unit or main body of two-position selector valve. CONSTITUTION:An annular rubber cushion 51 is seated on the left end of side plate 11 of the reciprocating drive unit 10, and also on the right side of sleeve 22 of the two-position selector valve 20. An annular rubber cushion 52 is seated on the left side of the sleeve 22 inside the main body 21 as well. The rubber cushions 51, 52 are positioned separately with a specified distance there between along the sliding direction of the movable piece 15 and spool 23, and are put in contact with the spool 23 for defining stop-position of the spool 23 and movable piece 15. |
