Abstract

See full text

An air motor has a source of pressurized air, two air chambers, a pilot valve and a directional control valve. The spool of the directional control valve is of the unbalanced type and includes a piston surface in continuous communication with atmosphere through an exhaust port and a pressurized restricted port in alternating communication with the large end of the spool and the piston surface. The alternating communication of the source of pressurized air through the restricted port is restricted relative to the continuous communication of the piston surface with atmosphere. At the point of shift of the directional control valve, the piston surface is in communication with the source of pressurized air through the restricted port.
