A hydraulic manifold has features adapted to the needs of hybrid vehicle applications. In one embodiment, multifunction valves selectively regulate fluid flow among primary and auxiliary flow paths. A normally closed butterfly valve is biased by a relatively small secondary biasing force against rotation in first and second (opposite) directions, and by a relatively large principal biasing force against rotation in the first direction past a transitional angular position at which the principal biasing force takes effect. An actuator selectively controls the transitional angular position and the magnitude of the principal biasing force. In the first direction, flow must overcome only the secondary biasing force to pass the valve. In the second direction, any flow sufficient to overcome the secondary biasing force but not the principal biasing force will divide into a first flow passing the valve and a second flow induced to enter an auxiliary path upstream. Additional flow causing the principal biasing force to additionally be overcome will substantially pass the valve as part of the first flow. This and other embodiments provide a manifold that is controllable to allocate flow among primary and auxiliary paths while remaining responsive to sudden large changes in flow independently of immediate control response.

An improved method of fabricating and discharging a pile configured battery which utilizes an electrically conductive flowing aqueous electrolyte. This is accomplished by use of a single piece hydraulic manifold plate which decouples the hydraulic performance parameters of the manifold from the electrical performance parameters. The manifold plate includes a configuration of hydraulic feed channels and distribution headers which separately account for electrical resistive effects and fluid viscous and dynamic pressure effects. Implementation of such manifold plates allow for improved energy conversion efficiency as well as utilization of multiple dissimilar fluids in a single battery cartridge cell discharge at greatly reduced complexity and cost.

A turf care system and method uses simultaneously fired pulses of high-pressure liquid jets of the mixture shot toward the ground. The liquid is mixed with dry grass seed shortly before being delivered to a high-pressure liquid/seed pumping system, which uses an accumulator and sequencing valve to produce at regular repetitive intervals pulses of the liquid/seed mixture under high pressure. The pulses are delivered to an elongated hydraulic manifold having multiple nozzles pointed downwardly, which are spaced from one another and the ground by predetermined distances. The momentum of the high-pressure jet of liquid/seed mixture issuing from each nozzle cuts through overlying vegetation to deposit the seeds into the crown of the soil at predetermined desired depth. Spray patterns are determined by nozzle orifice shape, and are preferably selected to provide a shallow knife slit-like opening or trench in the crown of the turf.

The piers support the structure upon eccentric brackets to transfer the structural load from the footing to the piles. Installation of the piers is followed by a continuous lift of the structure via hydraulic manifold.

A hydraulic shimmy damper that resolves drawbacks in several known shimmy dampers, such as damping characteristics that are dependent on oil temperature variations. The disclosed shimmy damper includes a hydraulic compensator (40) having an internal fluid volume that is significantly more important than a fluid volume expelled from the body of the shimmy damper when its piston moves fore and aft. The shimmy damper also includes a hydraulic manifold (30) arranged between the body and the hydraulic compensator and defining a transfer channel between chambers in the piston that is connected to the hydraulic compensator. The manifold receives interchangeable hydraulic cartridge-type valves (CV1,RV1;CV2,RV2) for metering the fluid flowing from the chambers to the transfer channel, and allows the fluid to freely enter the chambers from the transfer channel. The present shimmy damper is therefore much less sensitive to oil temperature variation under intense shimmy.
