Abstract
A reciprocating linear motor powered by one directional fluid flow is provided, having small external diameter, optimized for length, with few moving parts and effective seals, low mass and thus low inertia in direction changes. The motor provides reciprocating linear powered motion for use by attached equipment such as a pump, chisel, hammer, valve, or other machine requiring such power.
Claims20
A motor for providing powered reciprocating linear drive motion using a pressurized power fluid flow, the motor comprising:
- a housing having a first end and a second end;
- a first chamber provided in the housing proximate the first end of the housing, the first chamber having a first piston and operative to provide motive linear power during a power stroke of the first piston;
- a second compression chamber provided in the housing proximate the second end of the body, the second compression chamber having a second piston and operative to provide motive linear power during a power stroke of the second piston the second piston connected to the first piston such that a power stroke of the first piston causes an exhaust stroke of the second piston and a power stroke of the second piston causes an exhaust stroke of the first piston;
- the first chamber in fluid communication with the power fluid flow during a power stroke of the first piston and in fluid communication with a first exhaust port during an exhaust stroke of the first piston;
- and
- a second chamber in fluid communication with the power fluid flow during a power stroke of the second piston and in fluid communication with a second exhaust port during an exhaust stroke of the second piston.

A method of providing reciprocating linear motion powered by one directional fluid flow, the method comprising:
- providing a motor having a first piston defining a first chamber, a second piston defining a second chamber, the first piston and the second piston connected with a connecting rod so that the first piston and the second piston move in unison the powered piston pulling the other by the connection provided by the connecting rod, the first chamber and the second chamber positioned between the first piston and the second piston;
- supplying power fluid under pressure to the first chamber to drive the first piston through a power stroke and the second piston through an exhaust stroke;
- when the first piston reaches an end of its power stroke, supplying power fluid to the second chamber to drive the second piston through a power stroke of its own;
- and
- when the second piston has reached the end of its power stroke, again supplying power fluid to the first chamber.

A motor with a hydraulic/pneumatic valve for converting one directional flow of power medium into mechanical reciprocating motion, the motor comprising:
- a first piston, acting at the same time as an attaching platform to a mechanism to be powered by the motor, defining a first compression chamber and a second piston, acting at the same time as an attaching platform to the mechanism to be powered by the motor, defining a second compression chamber, the pistons connected together with a connecting rod so that the first piston and the second piston are forced to move in conjunction by tension on the rod;
- around the connecting rod, a valve comprising a reversing spool provided within a reversing sleeve each having a first end and a second end, the ends of the reversing sleeve and the reversing spool partially defining the first compression chamber and the second compression chamber;
- the reversing sleeve having a first end partially defining the first compression chamber and a second end partially defining the second compression chamber, operates to open the first compression chamber to the power fluid flow and open the second compression chamber to an exhaust vent during the first piston power stroke, and to open the second compression chamber to the power fluid and open the first compression chamber to the exhaust vent during the second piston power stroke;
- when the first piston is proximate an end of its power stroke, the second piston contacts the second end of the reversing spool, forcing the reversing spool towards the first piston, contacting the reversing spool and moving the reversing spool towards the first piston causing the reversing spool to place the second valve chamber in fluid communication with the at least one power fluid supply and venting the first valve chamber to exhaust and forcing the reversing sleeve towards the first piston;
- and when the second piston is proximate an end of its power stroke, the first piston contacts the first end of the reversing spool, forcing the reversing spool towards the second piston and causing the reversing spool to place the first compression chamber in fluid communication with the at least one power fluid supply and venting the second compression chamber and forcing the reversing sleeve towards the second piston;

- supplying power fluid to the first chamber to drive the first piston through a power stroke and the second piston through an exhaust stroke;
- when the first piston reaches an end of the power stroke, supplying power fluid to the second chamber to drive the second piston through a subsequent power stroke;
- and
- when the second piston has reached the end of the subsequent discharge stroke, supplying power fluid to the first chamber.
