摘要： A rotary servo valve comprising a housing portion (105) defining a cylindrical cavity (107) and a first layer of ports. The rotary servo valve further comprises two opposing indented sides and two opposing sides having an increased radius relative to the indented sides, each side of increased radius extending between the two indented sides. The spool portion (103) is mounted for rotation relative to the cylindrical cavity (107), from a neutral position so as to prevent fluid flow through the valve, to an open position in which a fluid flow path is provided.

摘要： A radial piston pump (1) comprising a rotor (2) mounted for rotation on a pintle (204) is disclosed. The rotor comprises a plurality of piston chambers (18), a piston (20) being mounted in each of said chambers (18) for reciprocal movement. The pump (1) comprises at least one supply flow path which connects the piston chambers (18) to a supply of low-pressure fluid, at least one exit flow path via which high-pressure fluid from the piston chambers (18) leaves the pump (1), and at least one auxiliary flow path which connects another component of the pump (1) to the piston chambers (18). The pintle (204) comprises a plurality of flow galleries (36), said plurality comprising at least one supply flow gallery (287) forming part of the supply flow path, at least one exit flow gallery (283) forming part of the exit flow path and at least one auxiliary flow gallery (285) forming part of the auxiliary flow path. Thus, radial piston pumps as disclosed herein may use the pintle as a fluid manifold providing fluid to or from the pistons and to or from at least one other component of the pump. A hydraulic power pack (270), a brake system (260), an active suspension system (170) and a flight control system (180) comprising such a pump, and a method of manufacturing such a pump is also disclosed.

摘要： A hydraulic manifold is formed in one piece. It comprises an exterior wall defining an inner space within which there is at least one flow gallery for conveying hydraulic fluid. The flow gallery provides a fluid flow path and is bounded by a boundary wall. The boundary wall is spaced inwardly from the exterior wall.

摘要： A suspension system (201) for an automotive vehicle comprising a hydraulic actuator (205) for mounting between a wheel assembly (209) and a body (207) of the automotive vehicle. The system also comprises a hydraulic system (210) configured to provide a supply of fluid to the hydraulic actuator. The hydraulic system is configured during normal operation to provide fluid at a static pressure greater than 7 MPa (70 Bar) to the hydraulic actuator. In embodiments of the invention, the hydraulic system comprises a plurality of gas accumulators (222, 232, 242), wherein the system is configured to transmit changes in fluid pressure between the hydraulic actuator, common flow path and gas accumulators such that the hydraulic actuator has a first stiffness when the hydraulic system is in the first configuration and a second, different, stiffness when the hydraulic system in the second configuration.
