Abstract: A hydraulic system includes a charge pump which supplies fluid to variable displacement main pump, a fluid reservoir and valve unit. The valve unit includes a hollow housing having a first end communicated with the reservoir and a second end communicated with the charge pump and the main pump. A housing valve land member is located between the first and second ends. A valve member is movably mounted in the housing. The valve member has a valve disk attached to first and second valve stems which project from opposite sides of the valve disk. The valve disk has a central position wherein the valve disk is received by the ring. The valve stems are slidably supported by stem support members at opposite ends of the housing. A hollow sleeve projects from an end of the valve unit. A spring is mounted in the sleeve and is engagable with an end of one of the valve stems and is biased to urge the valve member away from the sleeve.

Abstract: An illuminated rod standoff has a base with a recessed surface mountable to a wall, and an axially positioned fastener oriented normal to the recessed surface. The fastener engages a cap which centers a cylindrical sidewall resting on the recessed surface within a close-fitting peripheral edge. The cap closes an open end of the sidewall and provides, at mutual right angles, a pair of cap engagement features, one fixed to the fastener, thereby holding the cap securely to the cylindrical sidewall and the cylindrical sidewall to the base. The other feature receives a towel or tissue rod. A lamp is mounted on the base for transmitting light through the transparent cylindrical sidewall for illuminating a space.

The fastener engages a cap which centers a cylindrical sidewall resting on the recessed surface within a close-fitting peripheral edge. The cap closes an open distal end of the sidewall and provides a fastener holding the cap securely to the cylindrical sidewall and the cylindrical sidewall to the base. A towel or tissue rod my be engaged with the cap. A pair of lamps are mounted on the base for transmitting light through the cylindrical sidewall in a highly uniform manner.
