Abstract
An improved fluid actuated double action pullgun for installing blind rivets, particularly of the lock spindle type, which includes an improved shift valve mechanism. The shift valve employes a ballseat relief valve associated with pressure responsive plunger mechanism and spring responsive ball guide mechanism which respond to pressure differentials to directly monitor pressure in the trapped oil circuit and restrain 'shift piston' motion prior to shift. Premature 'shift piston' travel, which is a malfunction, is eliminated.
