摘要： A vehicular hydraulic system with a pump and first and second hydraulic applications arranged in series. The fluid upstream of the first application may be elevated to a first threshold pressure value. A pressure-dump valve is disposed downstream of the first application and fluid entering the valve flows through an inlet port, primary flow channel and outlet port of the valve to the second hydraulic application. The valve includes a valve member that axially slides within an elongate valve chamber, partitioning the primary flow channel from a low pressure volume. The valve also includes a low pressure port and a bypass port that diverts fluid past the second application. The valve member is biased into a position wherein fluid is diverted through the bypass port when the pressure in the primary flow channel exceeds a second threshold value. The first threshold value is greater than the second threshold value.

摘要： A vehicular hydraulic system having a hydraulic pump, a first hydraulic application, a second hydraulic application and a hydraulic reservoir arranged in series. A check valve is positioned to allow the flow of fluid from a point between the second hydraulic application and the pump to a point upstream of the second hydraulic application when the fluid flow upstream of the second application has been significantly reduced. The first and second applications may be a hydraulic brake assist device and a steering gear assist device. The use of such a check valve may also be employed with a hydraulic system having a priority valve for diverting a portion of the fluid flow to the second application when the pressure upstream of the first application is elevated above a threshold value. The hydraulic system may also employ a pump that has a discharge rate that falls within a predefined range.

摘要： A vehicular hydraulic system having a pump, first application, pressure-dump valve and second application arranged in series. The pressure-dump valve diverts a portion of the primary fluid flow past the second application when the pressure exceeds a threshold value. A valve member in the pressure-dump valve defines a pressure-reducing orifice that communicates fluid across the valve member. A check valve prevents flow through the pressure-reducing orifice when the pressure in the valve is below the threshold value. When the pressure exceeds the threshold value, fluid flows through check valve and the pressure reducing orifice resulting in the movement of the valve member and exposure of a bypass port thereby diverting a portion of the primary fluid flow past the second application. The check valve may be selectively variable to provide for the adjustment of the threshold value. A priority valve may also be provided upstream of the first application.

摘要： A vehicular hydraulic system with a pump and first and second hydraulic applications arranged in series. A valve is disposed whereby fluid from the pump flows through an inlet port, primary flow channel and outlet port of the valve to the first hydraulic application. The valve includes a body and a valve member that axially slides within an elongate valve chamber, partitioning the primary flow channel from a low pressure volume. The valve also includes a low pressure port and a bypass port. The bypass port is sealed from fluid communication with the valve chamber in a first position and is in fluid communication with the primary flow channel when the valve member is biased into a second position by a threshold exceeding elevated fluid pressure in the primary flow channel. Fluid discharged from the bypass port is diverted past the first application to the second application.

摘要： A vehicular hydraulic system having a pump, flow-splitting valve, first application and second application arranged in series. The flow-splitting valve diverts a portion of the primary fluid flow to the second application when the pressure exceeds a threshold value. A valve member disposed in the flow-splitting valve defines a pressure-reducing orifice that communicates fluid across the valve member. A one-way relief valve prevents fluid flow through the pressure-reducing orifice when the pressure in the valve is below the threshold value. When the pressure exceeds the threshold value, fluid flows through relief valve and the pressure reducing orifice resulting in the movement of the valve member and exposure of a bypass port to thereby divert a portion of the primary fluid flow to the second application. The relief valve may be selectively variable to thereby provide for the adjustment of the threshold value.

摘要： A modular computer chassis comprises a main chassis to which a motherboard is attached and a subchassis attachable to the main chassis. The subchassis is capable of having at least one computer component attached thereto such that the computer component is electrically connected to the motherboard. The computer component is thus separable from the main chassis by removing the subchassis from the main chassis. The subchassis contains those computer components subject to mechanical wear and most often requiring replacement, i.e. the power supply and disk drives. The subchassis is mechanically connected to the main chassis by using slots and tabs such that when the cover is in place upon the computer, then the subchassis is secured therein. The subchassis and the computer components disposed thereon thus form a module which is conveniently removable and replaceable such that those computer components most frequently requiring service is quickly removed and replaced by a person unskilled in computer repair.
