    摘要: A brake servo booster capable of operating in a traction control mode has a housing (100) containing a diaphragm assembly (500) which divides the housing into two chambers A and B. Supply of air to the diaphragm assembly is controlled by a valve mechanism which includes a reciprocable valve member (7) operatively connected to a force input member (5) actuated by a driver-operated control. The force input member includes two parts (11,12) connected respectively to the valve element and driver-operated control. The arrangement is such that operating force applied to the control is transmitted through both of the first and second input member parts (11,12) whilst a traction control operative mode is permitted by the second part (11) moving relative to the first part (12).

    摘要: A brake actuation apparatus includes a pneumatic booster and a master cylinder. A control rod in the booster responds to an input force for actuating a valve in the brake booster to develop an actuation force which is applied to a main hydraulic piston located in the master cylinder to pressurize fluid and effect a brake application. The main hydraulic piston includes a cylinder member with a bore therein for retaining a secondary hydraulic piston connected to the control rod. The cylinder member has at least one opening whereby pressurized fluid is communicated between the master cylinder and bore as function of a flow-rate reducer located in the one opening. The communication of fluid between the master cylinder and bore is always from the higher fluid pressure toward the lower fluid pressure. The fluid pressure in the bore acts on the secondary hydraulic piston to oppose the input force and thereby modify the time the valve remains opened by the input force and correspondingly the development of the actuation force for the pressurizing of fluid in the master cylinder.

    摘要: A fluid power apparatus is connected to a pressurized fluid supply and a conventional helm pump controlled by the helm of a vessel to shift the rudder. The apparatus comprises an actuator cylinder connectable to the rudder, and a servo cylinder and a main valve connected to the helm pump to pass fluid therebetween and between the actuator cylinder. The actuator cylinder and servo cylinder have respective bodies and piston rods, and portions of the servo cylinder and actuator cylinder are connected together for concurrent simultaneous movement along respective longitudinal axes. Valve shifting structure is responsive to a change in fluid signal from the helm pump applied to the servo apparatus. Fluid diverting structure is responsive to a threshold supply pressure so as to actuate the valve to stop flow of supply fluid when supply pressure drops below the threshold pressure. When pressurized fluid is available, the valve is actuated in response to a fluid signal from the helm pump and the actuator cylinder receives pressurized fluid from the valve and directs fluid back to the valve. When pressurized fluid is not available, the valve is actuated in response to a fluid signal from the helm pump and the valve is effectively by-passed and the actuator cylinder receives fluid from the helm pump and is actuated by manually applied pressures.

    摘要: A power steering control valve including relatively rotatable inner and outer valve members. A power steering resistance control system resists relative rotation between the inner and outer valve members with a force which varies as a function of variations in vehicle speed and steering demand. The power steering resistance control system includes a force transmitting member which is disposed adjacent to one end of the outer valve member. A spring force is applied against the force transmitting member urging it in a first direction along the axis of rotation of the valve members. Fluid pressure is applied against the force transmitting member to urge it in the first direction. A valve is operable to vary the fluid pressure applied against the force transmitting member. A solenoid valve controls the position of the valve as a function of vehicle speed and steering demand.

    摘要: The present invention relates to an assembly comrising a bulkhead (10) separating an engine compartment from a passenger compartment of a vehicle and a pneumatic booster (12) assisting the braking of the vehicle and comprising essentially a tube into which an operating rod (16) actuated by a brake pedal situated in the passenger compartment penetrates and a closed casing defining the pneumatic chambers of the booster disposed in the engine compartment. According to the invention the tube (14) is fastened to a collar (18) which has a diameter substantially smaller than that of the opening; the collar (18) is shaped in such a way as to have, at least in part, an end wall (20) parallel to the bulkhead; the collar (18) has a peripheral groove housing a ring (22); the ring (22) has, at least in part, an elastic edge (24) projecting outwards. Thus, when the booster is in position in the opening, the end wall (20) of the collar abuts against that face of the bulkhead (10) which is situated in the engine compartment and the elastic edge (24) of the ring forms a spacer between the other face of the bulkhead (10) and the groove.

    摘要: A torque generator steering device (10) is disclosed of the type including a gerotor displacement mechanism (19) and valving (9), by the rotation of an input shaft (1) results in a hydrostatic power assist to an output shaft (2). In parallel with the power assist path, the input shaft (1) is connected by a torsion bar (15) to a connecting shaft (3) which, in turn, is connected to the output shaft (2). The connections between the torsion bar (15) and the connecting shaft (3), and between the connecting shaft (3) and the output shaft (2) are substantially zero backlash mechanical connections, thus providing a main torque transmitting path in parallel with the power assist path. Below a predetermined level of input torque, rotation of the input shaft (1) results in an immediate and corresponding rotation of the output shaft (2), thus providing a manual steering mode.

    摘要: A method of manufacturing a tandem brake booster by selectively choosing a front shell having a first cylindrical body with first effective diameter, a transition shell having a second cylindrical body with a second effective diameter and a rear shell having a third cylindrical body with a third effective diameter. The cylindrical body of the transition shell is an integral component of an end wall which separates the interior the resulting tandem brake booster. The end wall has a peripheral ledge with a flange extending therefrom and a groove located on the flange connected to the second cylindrical body. An annular surface on the first cylindrical body is crimped into the groove on the flange while a corresponding annular surface on the second cylindrical body is crimped onto the third cylindrical to join the transition shell with the rear shell to form an integral unit.
