A hydraulic actuator for a vehicle suspension includes: a pump assembly including an electric motor coupled to first and second pumps to transfer hydraulic fluid to a discharge header; a first isolation valve having an elastomeric seat and configured to selectively block fluid flow from a port in fluid communication with a height-adjustable damper to the discharge header; and a second isolation valve having a metal seat and connected in series with the first isolation valve to selectively block fluid flow from the port to the discharge header. The first pump transfers hydraulic fluid from a supply fluid passage to a first discharge header, and the second pump transfers hydraulic fluid from the supply fluid passage to a second discharge header. A recirculation valve selectively controls fluid flow from the second discharge header to the supply fluid passage.

Suspension hydraulic lift actuator for axle trim height control

A blow-off metering valve for a hydraulic control unit assembly of a brake system including a valve seat. The valve seat includes a wall that extends about an axis between a first end and a second end. The wall defines a passage that extends axially between the first and second ends for transmitting a fluid through the valve seat. An annular flange extends axially from the second end of the wall toward the first end of the wall and tapers radially inwardly. A blocking member is axially movable toward and away from the annular flange for selectively creating a seal at the passage. A biasing element biases the blocking member toward the annular flange. The annular flange terminates at a distal end that is radially spaced from the wall. The annular flange defines at least one flow channel that extends axially for allowing fluid to bypass the blocking member.

Noise mitigating hydraulic control unit assembly for a vehicle braking system

An integrated air supply unit comprises a compressor housing, a pressure control unit (PCU) body, and a desiccant housing extending between the compressor housing and the PCU body. The desiccant housing defines a desiccant cavity holding a desiccant container for removing moisture from air passing therethrough. A piston is slidably disposed within a piston bore of the compressor housing. The PCU body defines a plurality of fluid passages with solenoid valves selectively controlling airflow therethrough. The integrated air supply unit may also comprise: a manifold, a discharge control valve, a compressor supplying pressurized air in a first pressurized air passage, a dryer configured to remove moisture from the pressurized air in the first pressurized air passage and to supply dried pressurized air in a second pressurized air passage, a supply control valve to control airflow between the second pressurized air passage and the manifold, and a piloted exhaust valve.

Integrated air supply unit

A piston pump assembly for pumping a fluid including a pump housing defining a bore. The pump housing further defines a fluid inlet and a fluid outlet and a fluid flow path extending therebetween for conveying the fluid from the fluid inlet to the fluid outlet. A piston is slidably disposed in the bore of the pump housing, and an eccentric engages the piston to propel the fluid through the fluid flow path. An inlet check valve and an outlet check valve body are disposed in the bore for only allowing the fluid to flow in one direction from the fluid inlet to the fluid outlet. A filter is disposed in the fluid flow path downstream of the inlet check valve and the outlet check valve body and adjacent to a damper orifice for filtering debris from the fluid before the fluid is conveyed to the fluid outlet.
