摘要： A suspension damper or shock absorber for a vehicle suspension system includes a piston assembly across which damping fluid is metered to control relative movement between the vehicle body and chassis. The piston assembly includes a piston plate in which a first set of openings are provided for fluid communication during the rebound stroke of the piston assembly and a second set of openings for communication of damping fluid during the opposite compression stroke. A wall circumscribes the first set of openings to define a recess receiving damping fluid from the first set of openings. A valve disc engages the wall and opens at a predetermined pressure differential. At pressure differentials less than the predetermined pressure differential, highly restricted flow is permitted through a bypass passage formed by a coined depression in the rim of the wall having a continuously curved, preferably semicircular cross section, to provide damping for low level inputs. The curved shape of the bypass passage reduces wear and tear on the coining tooling and also reduces turbulence in fluid flow for greater consistency in flow characteristics.

摘要： A dampening apparatus for dampening an actuating member over a wide array of temperatures. The present invention provides a fluid filled housing having a first chamber, a second chamber, and a passageway therebetween. A first piston is slidably received within the first chamber for movement from a pre-actuated position to an actuated position. A second piston is slidably received within said second chamber for movement from said pre-actuated position to said actuated position. A spring disposed within the second chamber biases the second piston toward said passageway and maintains a constant level of fluid pressure within the housing regardless of the temperatures of the fluid. An exhaust port is in communication with the second chamber wherein the second piston is disposed between the passageway and the exhaust port in the pre-actuated position, and wherein the exhaust port is located between the passageway and the second piston in the actuated position to allow the fluid to escape through the exhaust port. A positioning member is connected to the housing and the first piston for positioning and holding the first piston in the pre-actuated position wherein the positioning member releases the first piston under a predetermined load applied by an actuating member to the first piston allowing the first piston to be driven to the actuated position.

摘要： A gas spring includes a cylinder containing a fluid at least part of which is a compressed gas. The cylinder receives a piston that is affixed to a piston rod and divides the cylinder into two working chambers. The piston has a one-way valve that is cycled in response to the direction of motion of the piston and pressure-control valve consisting of a spring and a valve body. In a partial stroke region of the piston a bypass allows fluid flow past the one-way valve and the pressure-control valve. The partial stroke region is adjoined by a bypass-free stroke region, the gas spring being arrested in the bypass-free stroke region. The spring of the pressure-control valve has a temperature-dependent elastic force, the elastic force of the spring increasing with increasing operating temperature, owing to which the compressive force necessary for opening the pressure-control valve increases to an equal extent.
