Electronically controlled vehicle suspension system and method of manufacture
An air suspension system, comprising a manifold, defining a first and second port, each port defining a receiving region at the second end, wherein the first and second ports are arranged in a common plane, a channel intersecting the first and second port, a cavity intersecting each port, and a pressure sensor port, positioned between the first and second port, defining a sensor insertion axis normal to the common plane, the pressure sensor port separated from the first port, the second port, and the channel by a thickness; a first and second solenoid valve, each solenoid valve arranged within the cavity and coaxially arranged with the first and second ports, each solenoid valve comprising a connector; a pressure sensor arranged within the pressure sensor port, the pressure sensor comprising a connector; and an electronics module arranged parallel the common plane, the electronics module configured to electrically couple to the connectors.
SYSTEM AND METHOD FOR DETECTING VALVE OPERATING CONDITIONS
The present disclosure relates to a valve assembly including a valve moveable between an open position where hydraulic fluid flow is permitted between first and second ports of the valve and a closed position where hydraulic fluid flow is blocked between the first and second ports. A characteristic vibration is generated by turbulent hydraulic fluid flow within the valve when hydraulic fluid flow is first initiated between the first and second ports as the valve moves from the closed position toward the open position. The valve assembly also includes a controller for providing electrical current to control movement of the valve via a solenoid. The controller includes an accelerometer for sensing the characteristic vibration. The controller identifies an electrical current value of the electrical current at a time when the characteristic vibration is detected.

SYSTEM AND METHOD FOR CONTROLLING A VALVE MANIFOLD
A valve driver system for driving a plurality of valves of a valve manifold. The system includes a plurality of valve drivers, wherein each valve driver is configured to drive a zone of one or more valves of the manifold; and, a power board that separately powers the respective valve drivers such that the valve drivers are powered separately with a separate power source that can individually power the valve driver. A multiple safety zone valve driver system for driving a plurality of valves of a valve manifold. The system includes a plurality of valve drivers; a first safe PM output; and a second safe PM output. The first and second safe PM outputs are configured such that in response to a first type of safety event the first PM output shuts off power to the first one or more valve drivers and the second PM output maintains power to the second one or more valve drivers. A zoning adapter for adapting logical addresses of valve drivers to physical addresses of valves of a valve manifold. A conversion portion converts logical addresses to physical addresses of the valves in the different zones of the valve manifold with a spacing in one or more portions of the logical addresses.
Hydraulic block for a hydraulic assembly of a slip control system of a hydraulic vehicle brake system
A hydraulic block of a slip control system of a hydraulic vehicle brake system has receptacles for inlet valves and outlet valves of the slip control system arranged on a cover side, and receptacles for block valves, intake valves, and hydraulic accumulator on an opposite main side. All connecting bores for wheel brakes and a main brake cylinder are arranged on a transverse side and an eccentric chamber is arranged on an opposite transverse side of the hydraulic block.
Rotary drive device and a robot arm of a robot equipped therewith
A rotary drive device has a fluid-actuated rotary drive which has a drive housing and a drive unit rotatable about a main axis relative to the drive housing. The drive unit contains a pivot piston which divides two drive chambers from one another in the interior of the drive housing, which can be supplied with compressed air fluidic pressure medium controlled by a control fluid channel system, in order to cause a rotational movement of the drive unit. The rotary drive is equipped with a pressure detecting device, which enables pressure detection of the fluid pressure prevailing in the two drive chambers by means of pressure detecting channels formed separately with respect to the control fluid channel system. A robot arm is also proposed, which includes the rotary drive device as an arm joint.
Pressure booster
When a fluid is supplied to a first pressure-boosting chamber and/or a second pressure-boosting chamber of a pressure booster, either a first electromagnetic valve unit supplies a fluid discharged from a first pressurizing chamber to a second pressurizing chamber, or a second electromagnetic valve unit supplies a fluid discharged from a third pressurizing chamber to a fourth pressurizing chamber.
Leakage modulation in hydraulic systems containing a three-way spool valve
Hydraulic systems and associated methods configured to reduce leakage past a spool valve when the system is in a neutral state. Leakage reduction is achieved by shifting the spool valve within the spool bore. The amount of shifting can be controlled by a pressure controller that sets one or pressures in the system and actively/dynamically adjusts the system to achieve a desired pressure or set of pressures by shifting the spool valve.

A manifold for use with a fluid delivery system includes a fluid inlet defining a portion of a common channel, a fluid nozzle outlet, a plunger housing of an integrated valve, a collar of a coupling mechanism, and a mounting structure. The fluid inlet, fluid nozzle outlet, plunger housing, collar and mounting structure of the manifold are integrally-constructed. A manifold assembly for use with a fluid delivery system includes at least a first and a second manifold. Each manifold includes a fluid inlet defining a portion of a common channel, a fluid nozzle outlet, a plunger housing of an integrated valve, and a collar of a coupling mechanism. The fluid inlet, fluid nozzle outlet, plunger housing, and collar are integrally-constructed, and the fluid inlet of the first manifold is received by a portion of a common channel of the second manifold.
