摘要： A gas spring has a casing defining a chamber constructed to be filled with a gas under pressure, a piston rod received in the chamber for reciprocation between extended and retracted positions and having a free end projecting beyond the casing, a gas fill passage formed in the casing and through which pressurized gas is admitted into the chamber and a filler valve disposed in the fill passage to selectively permit the flow of gas through the fill passage. The filler valve has a body with a passage formed therethrough, a valve seat defined in the passage between opposed ends of the body and a poppet received in the passage and engageable with the valve seat to selectively permit gas flow through the filler valve and hence through the fill passage of the gas spring casing. The filler valve body preferably has mechanical threads formed in its exterior and constructed to be mated with complementary threads in the gas fill passage to firmly and releasably hold the filler valve within the fill passage. Preferably, an O-ring carried by the valve body provides a gas-tight seal between the valve body and the fill passage within a generally cylindrical portion of the fill passage. The valve body preferably has one or more integral tabs which retain the poppet within the valve body in assembly.

摘要： An air spring assembly has a pair of spaced end plates and a flexible sleeve extending therebetween forming an internal fluid chamber. One of the end plates is a bead plate which is crimped to an open end of the sleeve. An insert having an internally threaded hole is mounted in a central hole formed in the bead plate. An externally threaded coupler having a hollow bore is mounted in a central opening formed in an end member of an auxiliary reservoir and is threadably engaged with the internally threaded hole to mount the auxiliary reservoir in an abutting relationship on the air spring bead plate to provide a variable rate air spring. A fluid path is provided through the threaded connection for the flow of fluid between the air spring and auxiliary reservoir.

摘要： An air spring has a pair of spaced end members with a flexible sleeve ending therebetween forming an intervening air chamber. A partition is mounted in a hollow interior of one of the end members and forms an auxiliary air reservoir in the end member. A control valve having a moveable plunger is mounted on the one end member and is connected to a source of pressurized air. The plunger extends between the main air chamber and auxiliary reservoir and is controlled by a solenoid for selectively providing air passages between the pressurized air and the main air chamber and between the main air chamber and auxiliary reservoir to change the volume of the main air chamber to change the spring rate of the air spring.

摘要： The invention relates to a closed level control system for a vehicle. The closed level control system includes a pump which transfers a pressurized medium between a pressurized medium supply vessel (4) and pressurized medium chambers (2a to 2d). The input (8) of the pump (6) is connected to the supply vessel (4) and the output (10) of the pump (6) is connected to the pressurized medium chambers (2a to 2d) when the pressurized medium is to be pumped from the supply vessel (4) into the pressurized medium chambers (2a to 2d). If, in contrast, pressurized air is to be pumped from a pressurized medium chamber (2a to 2d) into the supply vessel (4), then the input (8) of the pump (6) is connected to the pressurized medium chamber and the output (10) of the pump (6) is connected to the supply vessel (4). The above-mentioned connections preferably take place via controllable directional valves (14, 18). The level control system makes it possible that the pump (6) has to always run only in one direction.

摘要： A gas spring and a method for filling a gas chamber of a gas spring does not require the use of a gas filling valve. Gas spring (5) includes a rod member (20), a cylinder main body (21), a gas filling chamber (22), first and second sealing members (23, 24), a plurality of pin members (25), and a plurality of slots (26). A gas filling implement (30) makes it possible to fill the gas filling chamber (22) with compressed gas in a simple and reliable manner without providing the gas spring (5) with a gas filling valve having a nonreturn valve. Consequently, the entire gas spring (5) is configured symmetrically about the axial center of the rod member (20), and its center of gravity is aligned with the axial center of the rod member (20), making it possible to prevent the gas spring (5) from inducing vibrations in the main shaft.

摘要： Filling valve for a gas bag installed in a space bounded by rigid walls, where the forces of a liquid medium, which is under pressure and which flows into and out of this space, act on this space. The gas bag serves as a compensation space, is filled with gas, and can be filled through a filling valve, which has an access channel aligned with an opening in the rigid wall. The access channel is located in a connector part connected to the gas bag, the connector part also being connected to a guide part resting against the inside surface of the rigid wall, the access channel being in effective connection with the opening in the rigid wall via this guide part.
