  • Patent number: 11400790
    Abstract: A hydraulic ride height actuator system for providing variation of a ride height at a front end of a vehicle is provided includes a strut and an actuator including a piston and a housing axially movable with respect to the piston. The housing is fastened to an upper end of the strut. The piston and the housing define a hydraulic chamber. An increase in a volume of the hydraulic chamber forces the housing upward to vary the ride height.

  • Patent number: 10351282
    Abstract: A valve device includes a control device adapted to control a valve without being supplied with electricity. The control device includes at least one rotatable control cam having an outer periphery with a concave and convex shape, and a driving device adapted to rotate the control cam only in a first rotational direction, out of the first rotational direction and a second rotational direction opposite from the first rotational direction, by being supplied with a pressurized medium. The valve is placed such that a switch portion comes in contact with the outer peripheral portion of the control cam, in order that the valve is opened and closed by the control cam being rotated.

  • Patent number: 10246182
    Abstract: A system, apparatus and method provide emergency differential braking for effecting braked steering of an aircraft. A brake input device is provided that not only allows for emergency and parking brake functions, but also enables differential braking. The brake input device (e.g., a parking and/or emergency brake lever, pedal, handle, etc.) can be used in a brake system including a brake system control unit (BSCU), one or more electro-mechanical actuator controllers (EMACs) and a brake assembly including one or more electrical actuators. Each EMAC is electrically coupled to one or more of the actuators so as to provide electrical power for driving the actuators. Each EMAC is also communicatively coupled to the BSCU so as to receive braking data therefrom. In an emergency, the input device sends braking signals directly to the brake actuators.

  • Patent number: 8701603
    Abstract: A control valve unit for a liquid circuit of an internal combustion engine, includes a valve housing (1) having at least one inlet opening (2) or outlet opening (2?) and at least two outlet openings (31, 32, 33) or inlet openings (31?, 32?, 33?) and at least two closing elements (41, 42, 43) actuated by a control device (22). The closing elements selectively open or close an associated outlet or inlet opening. The closing elements may be continuously adjusted between maximum open and closed positions. The control device (22) includes at least one displaceable or rotatable cam (6) and includes at least two cam tracks (71, 72, 73), each of which is assigned to a closing element (41, 42, 43) and acts on at least one driving pin (11) that is in contact with said closing element (41, 42, 43). The cams (6) are adjusted by an actuator (8).

  • Patent number: 8403004
    Abstract: A variable flow rate controller is provided herein. The controller may have a linearly traversable switch such that the controller is primed to flush air bubbles out of the fluid system of the controller prior to administering fluidic medication to a patient. Moreover, the controller may have a plurality of valves which may be independently opened and closed by a caming surface. To close the valve, a first seal may be disposed between offset inlet and outlet to prevent fluid from flowing from the inlet to the outlet. To open the valve, the first seal is disposed on one side of both of the inlet and outlet. Fluid if permitted to flow from the inlet to the outlet.

  • Patent number: 6405758
    Abstract: A valve driving apparatus includes a main body coupled with an inflow tube for introducing a fluid internally and a discharge tube for discharging the fluid. Valve members are movable within a predetermined range, for permitting the opening or the closing of apertures connected to one of the inflow tube and the discharge tube which is coupled with the main body. A driver drives the valve members, and the driver includes cam members having cam faces used for operating the valve members and a drive source for driving the cam members, wherein the valve members are operated by rotating the cam members to open the close the apertures.
