Abstract: A fluidic control system (1) for controlling a vehicle, which includes a controller (2) and a closed fluidic circuit. The circuit includes a pump (3) for pressurizing fluid in the circuit, valve means (40, 50, 60), an actuator (4, 5, 6) and a precharge accumulator (7). The valve means (40, 50, 60) is fluidly connected to the inlet and outlet of the pump (3) and the actuator (4, 6) is fluidly connected to the valve means (40, 50, 60) for selectively receiving pressurized fluid therefrom. The precharge accumulator (7) includes a movable member (73, FIG. 2) that describes a variable volume (71) fluidly connected to the circuit between the valve means (40, 50, 60) and the inlet of the pump (3). The system (1) also includes a sensor (70) for determining the position of the movable member (73) for estimating the quantity of fluid and/or detecting an abnormal pressure variation within the circuit.

Abstract: A bleeding device (1, 100) for bleeding air from a hydraulic system, which includes a bleed screw (2, 102) and a bleeding needle (3, 103) for unseating the bleed screw (2, 102) to enable any air trapped within the system to be bled. The bleed screw (2, 102) is receivable within a threaded bleed port (41) in a component of the system, such as a brake caliper (4). The bleed screw (2, 102) includes a socket (28, 128), a conical sealing face (27) and a radial fluid passage (24) between the sealing face (27) and the socket (28, 128). The bleed needle (3, 103) includes a plug (34, 134) for releasable engaging receipt within the socket (28, 128) of the valve member and a fluid passageway (31) which is in fluid communication with the radial fluid passage (24) of the bleed screw (2) when the plug (34, 134) is received within the socket (28, 128). The bleed screw (2, 102) is movable, in use, between a sealed position in which the sealing face (27) seats against the sealing face (43) of a bleed port (41) and a bleeding position in which the sealing face (27) is unseated to open fluid communication between the bleed port (41) and the fluid passageways (24, 31).

Abstract: A brake caliper (1) including a caliper body (2) with a pair of spaced limbs (3), a pair of end bridging members (4) each joining together a respective end of each limb (3) and an intermediate bridging portion (5) between the bridging members (4) and joining together a respective intermediate portion of each limb (3). Each limb (3) includes a hydraulic circuit (30) including fluidly connected hydraulic cylinders (31a, 31b, 31c) within which respective pistons (6a, 6b, 6c) are received. The hydraulic circuits (30) are fluidly connected together by a fluid channel (7). Part of the fluid channel (7) is formed in the intermediate bridging portion (5) and extends diagonally across the space between the limbs (3) and between the bridging members(4).
