Abstract

By selectively anchoring either end of the cylinder adder assembly of the illustrated positioning mechanism, it may be employed to discretely position either one of a pair of piston members positioned diametrically opposite to each other. The piston rod of each piston member is connected to a sliding valve element disposed in a valve chamber. Fluid under pressure is supplied to the chamber causing the valve elements to be biased inwardly toward the home position of the cylinder adder assembly.

Positioning Mechanism

By selectively anchoring either end of the cylinder adder assembly of the illustrated positioning mechanism, it may be employed to discretely position either one of a pair of piston members positioned diametrically opposite to each other. The piston rod of each piston member is connected to a sliding valve element disposed in a valve chamber. Fluid under pressure is supplied to the chamber causing the valve elements to be biased inwardly toward the home position of the cylinder adder assembly.

To position the left-hand piston, the right end of the cylinder adder assembly is anchored which causes the cylinder adder to extend to the left when suitably addressed. Similarly, to position the right-hand piston, the left end of the cylinder adder assembly is anchored which causes the cylinder adder to extend to the right when addressed.

If desired, the piston chamber may also be supplied with fluid under pressure by means of a passage extending through the piston rod in the piston.
