ABSTRACT:
A pneumatic motor including a motor body having a piston chamber with opposed chamber ends, at least two valve chambers, an inlet for flowing a pressurized fluid into the piston chamber and each of the at least two valve chambers, a number of outlets provided in the housing for exhausting the pressurized fluid from the piston chamber and each of the at least two valve chambers. The motor also includes a three-way valve member adapted to be located in each of the at least two valve chambers, the valve members each have at least one open end and at least one port formed along the valve member body. A spool member is located in one of the valve chambers, each spool member has a first end adapted to be located in the open end of the valve member. The spool members are adapted to be movable in a first direction relative to the valve member to permit pressurized fluid to be supplied to the piston chamber and also in a second direction relative to the valve member to permit the pressurized fluid in the piston chamber to be exhausted from the chamber. A piston is movable in a reciprocating manner in the main chamber in response to movement by the spools relative to the three-way valve members.
