A damper includes a pressure tube extending about a longitudinal axis and defining an inner volume. The damper includes a piston attached to a piston rod and slidably disposed within the pressure tube. The piston divides the inner volume of the pressure tube into a first working chamber and a second working chamber. The damper includes a fluid connector having a first wall and a second wall, each elongated along the longitudinal axis and sealed to the pressure tube. The fluid connector has a third wall elongated along the longitudinal axis and extending from the first wall to the second wall. The pressure tube defines an opening at the first working chamber, and the third wall of the fluid connector defines an opening spaced from the opening of the pressure tube. The first wall, the second wall, and the third wall define a passage extending from the opening of the pressure tube to the opening of the third wall.

A bumper cap assembly for an electrically adjustable hydraulic shock absorber. The bumper cap assembly includes a printed circuit board assembly and a bumper cap. The printed circuit board assembly includes power drive electronics and is electrically coupled to the shock absorber. The bumper cap defined a gap, wherein the printed circuit board assembly is housed within the gap.

A gas spring and gas damper assembly includes a gas spring and a gas damper. The gas spring includes a flexible spring member with opposing end members secured thereto and at least partially defining a spring chamber. The gas damper includes an inner sleeve that is at least partially received within one of the end members and at least partially forms a damping chamber. A damper piston assembly is received within the damping chamber and secured to the other of the end members. An elongated damping passage fluidically connects the damping chamber and the spring chamber. Suspension systems and methods are also included.

A load absorber dampens relative movement between subsea bodies. The load absorber is cooperable with an actuating member such as a male piston element or a female cup on an opposed subsea body. The load absorber comprises a hollow structure defining an internal flow path for water. A flow restrictor acting on the flow path restricts a distal flow of water along the flow path from a proximal opening, caused by convergence between the actuating member and the load absorber. The flow restrictor comprises a shuttle element to restrict the flow path that is mounted to the structure for automatic movement from a first state to a second state in response to an increase in water pressure at the proximal opening. In the first state, the shuttle element effects greater restriction of the flow path than in the second state.

Disclosed is a variable damping force shock absorber including a tube cylinder having an inner tube filled with a fluid and an outer tube, a valve housing coupled to a piston rod in the inner tube and having a connection flow path formed therein, a first piston valve coupled to the outside of the valve housing to partition the inner tube into a compression chamber and a rebound chamber, and a second piston valve provided inside the valve housing, wherein the valve housing includes a magnet provided at an upper portion thereof and connected to the piston rod, and a plunger disposed between the magnet and the second piston valve at a lower portion thereof to selectively open and close the connection flow path by a magnetic field of the magnet, and wherein the fluid passes only through the first piston valve when the plunger closes the connection flow path, and the fluid passes through the first piston valve and the second piston valve when the plunger opens the connection flow path.

A damper assembly includes an outer cylinder, an inner cylinder positioned at least partially within the outer cylinder, a cap coupled to the inner cylinder, and a plunger positioned radially inward from the inner cylinder and coupled to a rod. The plunger, the cap, and an interior of the inner cylinder at least partially define a first chamber. The suspension system further includes a passage extending through the rod and fluidly coupled with the first chamber, a piston coupled to the inner cylinder and extending radially outward toward the outer cylinder, a first port in fluid communication with the plunger, the cap, and the inner cylinder through the passage, and a second port in fluid communication with the piston, the inner cylinder, and the outer cylinder. The piston, an exterior surface of the inner cylinder, and the outer cylinder at least partially define a second chamber.

The damper assembly includes a tubular member, a rod, a primary piston, a secondary piston, and a resilient member. The tubular member includes a sidewall and a cap positioned at an end of the sidewall. The sidewall and the cap define an inner volume. The sidewall includes a shoulder separating the tubular member into a first portion and a second portion. The resilient member is disposed between the secondary piston and the cap and thereby is positioned to bias the secondary piston into engagement with the shoulder.

A shock absorber includes a first portion and a second portion that reciprocate relative to one another. The shock absorber includes a gas spring chamber defined between an interior wall and a plunger. A seal including a lip portion minimizes gas pressure loss and friction between the two portions.
