Abstract: A passive/active hydraulic exercise device having a base portion, an upright support and a pivot bard is selectively placed in either a passive push and pull type resistance mode or an active velocity type mode. In the passive mode, a pump can be off or on during “idling”. A solenoid valve is energized to an open position, and a servo valve sets a resistance for the fluid flow in the system. A check valve compensates for the differential areas of the cylinder. The active mode is useful for physical therapy applications. In this mode, a constant cycling operation is provided at absolute minimum force levels. The load cell senses the actual force generated, and the position feedback senses actual movement of the exercise bar. As long as the subject is providing enough force to move the bar, the feedback device confirms movement to the computer which adjusts the resistance of the electronic pressure control valve to a value which will allow the subject to continue moving the bar.

Abstract: A leveling valve responsive to changes in vertical distance between a vehicle chassis and its axle. A valve body has an internal chamber with which a supply port communicates for delivering air from a pressurized air tank. One or more delivery ports extend through the valve body in communication with the chamber, each for connection to an air spring. An exhaust port also communicates with the chamber. A piston is reciprocable within the chamber between a normal position in which the valve is closed, a second position in which the valve is open communicating the supply port with one or more delivery ports, and a third position in which the supply port is normally closed by the air source pressure but a passage communicates the one or more delivery ports with the exhaust port. The piston has a passage through it that is used in the third position. Reciprocation of the piston is controlled by a guide having a transverse slot in which a camming pin projects.
