Abstract: In a remote controlled fluid piston-piston rod type damper (10), a ported damping piston (38) divides a cylinder (26) into upper and lower chambers (40, 42), a ''spoiler'' sleeve (96) reciprocably encircles an electrical coil (72), a pair of shoulders (54, 64) extend radially from the piston rod, and a pair of precompressed coil springs (44, 46) position the piston between the shoulders for reciprocable axial movement relative to the piston rod (36). An electrically controlled valve operates to regulate flow between the chambers in response to relative reciprocable motion between the piston rod (36) and the piston (38), the electrical coil being energized by an alternating voltage input whereby to generate a magnetic field about the sleeve. Movement of the spoiler sleeve through the magnetic field changes the current in the electrical due to self-inductance, and a remote control module (108) generates a control signal, in response to the change in coil current, to actuate the electrically controlled valve whereby to regulate flow between the chambers.

Abstract: A sealing system (12) for a hydraulic actuator (10) operable to selectively change the frictional sealing force exerted on a piston rod (22) in response to fluid pressure acting on the sealing system. A first seal member (72) operable for permitting a predetermined amount of fluid to leak from working chamber (16) to leakage chamber (76). A flow control valve (84) controls the flow of fluid from the leakage chamber (76) to a reservoir (86). A pressure responsive seal assembly (90) is operable to inhibit leakage of fluid from the leakage chamber (76) to the exterior of the hydraulic actuator (10) and is energizable in response to an increased fluid pressure within the leakage chamber (76) for generating increased frictional engagement with the piston rod (22) for preventing the vehicle body to sink during an extended stationary period of time. Furthermore, the pressure responsive sealing assembly (90) generates a reduced frictional engagement with the piston rod (22) when fluid pressure in the leakage chamber (76) is relatively low.

Abstract: In vehicles, different driving characteristics have required the use of shock absorbers having a complexity of adjustable parts. To reduce such a complexity of parts, a shock absorber has its valve and actuator located within the shock absorber's piston and piston rod assembly (40, 38) which is mounted for reciprocation in cylinder (42), the piston (40) dividing the cylinder (42) into upper and lower chambers. A floating inner piston (122) is slidably disposed in a fluid reserve chamber (120) of the piston (40) for movement between first and second positions to selectively open and close fluid passages (142, 144, 146) associated with the assembly to vary the resistance to damping fluid moving through the assembly and between the chambers. The floating piston (122) movement is controlled by a solenoid-plunger and, when the floating piston is in a first position, provides "soft" compression and rebound strokes and, when the floating piston is in a second position, provides "firm" compression and rebound strokes.

Abstract: A direct acting hydraulic damper (20) comprising an internal, non-contact sensing means for the direct measurement of relative velocity between the piston (44) and the cylinder (40) of the damper (20). The damper (20) comprising a cylinder (40) forming a working chamber (42) operable to store damping fluid. A piston (44) is disposed within the cylinder (40) defining an upper and lower portion of the working chamber (42). The damper (20) further comprises a first transducer (66) for emitting ultrasonic waves within the lower portion of the working chamber (42). The ultrasonic waves emitted by the first transducer (66) are reflected by a base valve (52) or end surface of the cylinder (40) facing the transducers (66, 68) and are received by a second transducer (68). A frequency detection circuit (82) determines the difference in frequency between the emitted and reflected ultrasonic waves and generates an output in response thereto. A computer (90) then calculates the relative velocity of the piston (44) with respect to the base valve (52) or end surface, based on the Doppler principle. The velocity signal (V) is then used for automatic control of suspension parameters according to predefined algorithm.

Abstract: Vehicle suspension apparatus (10) operating between the sprung and unsprung masses of a vehicle includes a pendular anti-roll bar (12) connected to the vehicle, and a pair of links (30, 34) which connect the bar (12) to the wheels. One and the other link (30, 34), respectively, is extensible and inextensible, with the extensible link (34) comprising a selectively controllable hydraulic piston-cylinder assembly (44) having first and second flow paths (136, 138), and valve means (82) which upon command automatically locks the piston (66) at a midstroke position, depending on the flow of fluid in the passages (136, 138). The flow paths (136, 138) allow the user to select either of two roll stiffness levels (i.e., high and low) and provide automatic convergence of the piston (66) to its locked midstroke position (high roll stiffness hard ride) upon command.
