An air spring includes a sleeve, a jounce bumper, and a bump cap. The sleeve defines a chamber. The jounce bumper is fixed relative to the sleeve in the chamber. The bump cap is moveable relative to the jounce bumper from a first position to a second position in contact with the jounce bumper. The jounce bumper includes a valve moveable by the bump cap to a closed position when the bump cap moves to the second position.

An inertia-actuated valve assembly includes a valve housing, a valve body and a biasing element. The valve housing includes a groove that has an open end fluidically accessible from along one side thereof. The valve housing includes a flow channel extending therethrough in fluid communication with the groove from along an opposing side of the valve housing. The valve body is positioned within the groove of the valve housing such that the valve body and the valve housing are axially co-extensive along at least a portion thereof. The biasing element operatively engages the valve body and generates a biasing force urging the valve body in a first axial direction. The biasing force is greater than a predetermined dynamic gas pressure threshold value multiplied by a pressure area and is less than or approximately equal to a valve body mass multiplied by 2.5 times the nominal acceleration due to gravity.

A sealing apparatus for an air spring device for sealing a primary volume of the air spring device in particular a working volume of the air spring device, with respect to a secondary volume, including a main body, and a sealing element configured on the circumference of the main body, the sealing element configured such that, in a state in which it is mounted in the air spring device, the sealing element is transferred from a sealed position, in which the sealing element seals the primary volume with respect to the secondary volume, into a released position, in which air passes the sealing element, when a pressure difference between the primary volume and the secondary volume, which pressure difference is set with respect to the secondary volume as a negative pressure in the primary volume, exceeds a threshold value.

An air spring for a heavy-duty vehicle axle/suspension system comprising a piston, a bellows, and an intermediate chamber integrally formed with the bellows. The bellows has an upper portion, a top plate, and a bellows chamber and is connected to the piston by a band, a bead-in-groove connection, and/or a bayonet connection. The upper portion is reinforced to prevent the bellows chamber from increasing in volume. The intermediate chamber has an optimally sized top plate and a support structure and extends from the piston into the bellows chamber. The intermediate top plate is formed with means for restricted fluid communication between the bellows chamber and the intermediate chamber. The means for restricted fluid communication is not obstructed when it contacts the bellows top plate during jounce events. The support structure is optimized in relation to the top plate.

Support and carrier assemblies are dimensioned for securement along a damper housing and dimensioned to operatively support an end member of a gas spring assembly on the damper housing as well as to form a substantially fluid-tight connected between the end member and the damper housing. The support and seal assembly can include a seal assembly with a seal carrier and at least one sealing element. The seal carrier can be dimensioned for securement along the damper housing. The at least one sealing element can be dimensioned sealingly engage the seal carrier and one of the end member and the damper housing to at least partially form the substantially fluid-tight connection therebetween. End member assemblies including such support and carrier assemblies are included. Gas spring and damper assemblies as well as suspension systems are also included.

An air spring strut for a motor vehicle comprising an air spring with a shock damper for the spring-cushioning and damping of oscillations of a motor vehicle chassis, wherein the air spring comprises an air spring cover and a rolling piston, wherein a rolling bellows of elastomer material is clamped in an airtight manner between the air spring cover and the rolling piston, wherein the air spring cover comprises a damper bearing receptacle in which a damper bearing of the shock damper is arranged, and wherein the air spring cover comprises a clamping base to which a first end of the rolling bellows is attached, wherein at least the damper bearing receptacle of the air spring cover is produced from a plastic material.

A combined air spring system includes an upper cover plate, an air bag, an upper end plate and a lower end plate. An outer periphery of the upper cover plate is connected with an outer periphery of the upper end plate through the air bag. A low-position sand clock elastomer is connected between the upper end plate and the lower end plate . A pressing plate is installed at a bottom portion of the upper cover plate, and a high-position elastomer is connected between the upper cover plate and the pressing plate. A limiting table is arranged at a bottom portion of the pressing plate. A limiting groove is formed in a top face of the upper end plate. The limiting table is located in the limiting groove in a deflated state.

An apparatus for isolating bubbles from a liquid comprises at least a main body; an inlet tube and an outlet tube disposed at a side of the main body which includes an accommodation chamber and a column disposed atop, the inlet tube is formed with an aperture within the accommodation chamber, and the outlet tube is disposed at a position below the inlet tube; and a coupling tube disposed within the accommodation chamber, and includes a first end connected to the inlet tube and a second end corresponding to and separating from the outlet tube by a gap. During use, a liquid dispersed with bubbles is introduced through the inlet tube. The bubbles pass through the aperture along with a small portion of the liquid and ascend toward a top of the accommodation chamber and are then collected by the column.

An inertia-actuated valve assembly includes a valve housing, a valve body and a biasing element. The valve housing includes a groove that has an open end fluidically accessible from along one side thereof. The valve housing includes a flow channel extending therethrough in fluid communication with the groove from along an opposing side of the valve housing. The valve body is positioned within the groove of the valve housing such that the valve body and the valve housing are axially co-extensive along at least a portion thereof. The biasing element operatively engages the valve body and generates a biasing force urging the valve body in a first axial direction. The biasing force is greater than a predetermined dynamic gas pressure threshold value multiplied by a pressure area and is less than or approximately equal to a valve body mass multiplied by 2.5 times the nominal acceleration due to gravity.

An air spring includes a sleeve, a jounce bumper, and a bump cap. The sleeve defines a chamber. The jounce bumper is fixed relative to the sleeve in the chamber. The bump cap is moveable relative to the jounce bumper from a first position to a second position in contact with the jounce bumper. The jounce bumper includes a valve moveable by the bump cap to a closed position when the bump cap moves to the second position.
