Abstract

A control system for a reciprocating device. The control system includes a switching valve having a fluid supply inlet, an exhaust outlet, a restrictor on the exhaust outlet, a drive line, a valve operable to connect one of the exhaust outlet and the fluid supply inlet to the drive line and a toggle for operating the valve, the toggle being movable by motive force through an arc between a first position in which fluid flow is from the fluid supply inlet to the drive line and a second position in which fluid flow is from the drive line to the exhaust outlet, the toggle passing through a middle position where fluid flow may flow from the drive line to the exhaust outlet and from the fluid supply inlet to the drive line.
A reciprocating device is provided that is operable to move in a first direction due to fluid pressure in the drive line and a second, opposed, direction due to a motive force activator when pressure in the drive line is reduced (exhausted). A trigger on the reciprocating device moves with the reciprocating device. A connector is disposed between the trigger and the toggle. The connector being operable to move the toggle into the first position when moving in the second direction and to move the toggle into the second position when moving in the first direction. The connector includes a spring arranged to transmit forces from the trigger to the toggle when the trigger is moving in the first or second direction (or both, with two springs), the spring storing energy while moving in the first or second direction to force the toggle through the middle position.
