A vehicle damper assembly is disclosed. The damper includes a cylinder having an inner diameter (ID). A rod and a piston, the piston coupled to the rod and configured to divide the cylinder into a compression side and a rebound side. An electronic valve assembly including an electronic valve body coupled with the rod on the compression side of the piston. The electronic valve body having an electronic valve body outer diameter (OD). A boost valve having a boost valve body, a boost valve area located between the electronic valve body and the boost valve body, the boost valve having a boost valve OD. The boost valve OD is larger than the electronic valve body OD, such that the boost valve is configured to allow the electronic valve assembly to operate within said cylinder ID that is too large for the electronic valve body OD.

An electronically controlled internal damper includes an outer housing reciprocated in a cylinder and partitioning the cylinder into an upper chamber and a lower chamber, an inner housing disposed inside the outer housing and forming a main flow path which makes the upper chamber and the lower chamber of the cylinder communicate with each other, a main poppet disposed in the inner housing to be movable up and down, thus opening or closing the main flow path, a pilot poppet configured such that at least a portion thereof is accommodated in an upper portion of the main poppet and adjusting an opening force of the main flow path according to a control current applied to a valve, and a soft valve coupled to a lower portion of the outer housing.

A vehicle suspension damper is described. The vehicle suspension damper includes: a pilot valve assembly; a primary valve; and an adjuster, wherein the pilot valve assembly meters fluid to the primary valve, and the adjuster moves the primary valve.

Provided is a valve device and a shock absorber that can prevent them from being in a failure state at the normal time and can freely set a passive valve even when both pressure control and passage opening/closing are performed by a solenoid valve. For this reason, the valve device includes a first passage and a second passage connected downstream of the pressure introducing passage, a solenoid valve that opens the first passage to control the upstream pressure and closes the second passage when energized, and that closes the first passage and opens the second passage when not energized, and a passive valve provided downstream of the solenoid valve in the second passage.

A shock absorbing device includes a control unit and a transmission unit. The control unit includes a first shaft and a second shaft which freely and rotatably extends through the first shaft. The first end of first shaft and the first end of the second shaft protrude beyond the shock absorbing device. The transmission unit includes a first bevel gear and a second bevel gear. The second shaft freely and rotatably extends through the first bevel gear. When the first shaft is rotated to drives the first bevel gear, the first bevel gear drives the second bevel gear to adjust the recovery damping of the shock absorbing device. When the second shaft is rotated, the compression damping of the shock absorbing device is adjusted. The cooperation of the first and second bevel gears makes the operation of the shock absorbing device be smooth and stable.

Disclosed herein is a shock absorber comprising a cylinder, a rod, a main damping piston, the main damping piston coupled to the rod and configured for operation within the cylinder, the main damping piston configured to divide the cylinder into a compression side and a rebound side, a body cap disposed at one end of the cylinder, wherein the body cap has a second inner diameter greater than an inner diameter of the cylinder, an internal floating piston disposed within the body cap, configured to divide the body cap into a first side and a second side, and a base valve piston disposed to separate the compression side from the first side.

An electrically controlled valve for a shock absorber. The valve comprises a piston providing a primary fluid channel for damping fluid and a housing in which a piston holder is provided with an internal secondary fluid channel for damping fluid. Fluid flow (23) through the secondary fluid channel for damping fluid. Fluid flow through the secondary fluid channel is controlled by a spool movable within the piston holder wherein the movement of the spool is enabled by an electrically controlled actuator. Fluid flow through the secondary fluid channel is controlled by restriction at the inlet of the secondary fluid channel the inlet comprising one or more radial holes through the piston holder.

A suspension monitoring and adjustment system for an off-road vehicle includes a distance sensor arranged to measure shock displacement of a suspension of the vehicle. The system may include an output device configured to output shock displacement data generated by the distance sensor and a processor or programmable circuit operable to produce a visual representation of the shock displacement data output by the output device. The system may include a processor or programmable circuit operable to generate an adjustment signal based on shock displacement data generated by the distance sensor and a suspension adjuster arranged to adjust the suspension of the vehicle in response to the adjustment signal.

A vibration damper with an adjustable damping force may comprise an inner cylinder having at least one working chamber, an outer cylinder that surrounds the inner cylinder, and at least one damping valve element that in terms of flow is connected via a flow connection to the working chamber. An adapter sleeve may guide the flow connection, with the adapter sleeve being inserted in the inner cylinder on an internal circumference of the inner cylinder. The flow connection may be guided into the damping valve element by way of a flow opening that is configured in a wall of the inner cylinder.

A pressure regulation valve including a multiplicity of function modules, preferably pre-mounted function modules, with a pilot stage module and an actuator module, which are firmly interconnected via a press connection, preferably exclusively a press connection, and which preferably have a central axis. A shock absorber with at least one pressure regulation valve.
