Abstract: A hydrostatic power steering system is provided of the type including a steering control unit (3) operated by an input such as a steering wheel (1) to control flow from a source (8) to a steering cylinder (7). The source is operated in response to an electrical signal from a controller (82), controlled by a sensed pressure at a pressure detection port (64). The pressure at the port (64) is communicated from the main fluid path of the steering control unit (3), downstream of the fluid meter (18) when the spool (21) and sleeve (22) are relatively displaced. In systems in which the system reservoir (R) is at an elevated ("regulated tank") pressure, the pressure detection circuit is drained through a variable orifice (70) to a drain port (66), which is in communication with a sump (S) maintained at substantially atmospheric pressure. As a result, the steering system responds at a lower steering pressure, and the initial steering is smoother.

Abstract: Devices for supporting an LPG tank bracket between overhead guard rear pillars of an LPG fork lift. Each supporting device comprises a mounting member which is removably mounted around the rear pillar and a member for supporting one end of the tank bracket, the supporting member being welded on the mounting member. Therefore, the LPG tank bracket can be supported between the pillars, even if the rear pillars are not specially designed for an LPG fork lift.
