    Abstract: A RECIPROCATING PISTION AIR MOTOR WITH A PILOT PISTON OPERATED SLIDE VALVE THAT ADMITS AIR ALTERNATELY TO OPPOSITE ENDS OF THE DRIVE CYLINDER OF THE AIR MOTOR THROUGH SEPARATE STRAIGHT AIR PASSAGES WHICH ALSO SERVE AS EXHAUST PASSAGES. THE POSITION OF THE DRIVE PISTION IS SENSED BY STEMS EXTENDING FROM SPOOL VALVES POSITIONED AT OPPOSITE ENDS OF THE DRIVE PISTON CYLINDER CHAMBER. THE SPOOL VALVES CONTROL THE SUPPLY AND EXHAUST TO THE PILOT PISTON, THEREBY CONTROLLING THE SLIDE VALVE AND CONSEQUENTLY PRESSURE TO THE DRIVE PISTON.

    Abstract: Apparatus and method for heating fluid under pressure. The apparatus aspect of the disclosure includes a member that defines a chamber in which a source of heat and a radiator are located. The outer surface of the radiator defines pathways through which the fluid flows in the apparatus in order to be heated. A gap is provided between the radiator and the member so that fluid disposed in the gap partially insulates the fluid flowing in the pathways. Insulation is provided around the member and a thermostat is mounted in a cavity defined by a housing attached to the radiator so that the fluid is uniformly heated to a constant, predetermined temperature. A filter is held in an outlet assembly that automatically retains fluid in the chamber when the filter is removed for cleaning.
