ABSTRACT:
A reciprocatory air motor has a main plunger valve the position of which controls the flow of air to opposite sides of a main motor piston. Positioning of the plunger valve is itself controlled by a pair of cushion pistons carried on the piston rod of the motor. A space between the cushion pistons is used for the compression of air to effect absorption of the kinetic energy of the moving parts of the motor at opposite ends of the stroke.
