摘要： A demand responsive flow regulator valve for use with a power steering pump and steering mechanism has a valve spool slidably disposed in a housing and responsive to a pressure differential across an orifice for the purpose of bypassing excess pump flow. The flow control orifice establishes pressure signals proportional to pump flow to the steering mechanism. The pressure signals are operative on the valve spool to control the bypassing of excess pump flow. A spring loaded metering rod disposed in the flow control orifice increases the effective area of the orifice when pressure demand at the steering mechanism increases thereby increasing the fluid flow to the steering mechanism while simultaneously decreasing the bypass flow.

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 and first and second hydraulic applications arranged in series. A dual relief valve defines first and second flow channels, a passageway and a bypass port. The first flow channel is disposed between the hydraulic pump and the first hydraulic application and the second flow channel is disposed between the first hydraulic application and the second hydraulic application. A first valve member controls fluid flow through the passageway and allows fluid flow from the first to the second flow channel through the passageway when fluid pressure within the first flow channel exceeds a first threshold pressure. A second valve member controls fluid flow through the bypass port and allows fluid flow from the second flow channel to a return line through the bypass port when fluid pressure within the second flow channel exceeds a second threshold pressure.

摘要： A hydraulic fluid reservoir assembly is disclosed. The reservoir assembly includes a reservoir housing defining a fluid chamber and a baffle member. The baffle member is disposed within the fluid chamber above the inlet and defines a central opening disposed radially inwardly of the reservoir housing. The central opening provides fluid communication between an inlet zone below the baffle and an upper zone above the baffle. The hydraulic fluid introduced through the inlet is directed to flow circumferentially along a radially outer section of the inlet zone whereby air entrained in the hydraulic fluid collects in a central portion of the inlet zone and is communicated to the upper zone thereby deaerating the fluid. A means for forming a substantially fluid tight seal between the reservoir housing and the baffle member is provided along an outer radial edge of the baffle member. A method of manufacture is also disclosed.

摘要： A vehicular hydraulic system having a hydraulic pump, a first hydraulic application and a second hydraulic application arranged in series. A relief valve is arranged parallel with the second application to allow fluid to bypass the second application when fluid pressure upstream of the second application exceeds a threshold value. The first and second applications may be a brake assist device and a steering gear assist device. The hydraulic system may also include a priority valve for diverting a portion of the fluid flow to the second application when the pressure upstream of the first application exceeds a threshold value. The threshold value for the first application may be greater than the threshold value for the second application. The hydraulic system may include a pump having a discharge rate that falls within a predefined range. A check valve may also be arranged parallel with the relief valve and second application.

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 can be quickly removed and replaced by a person unskilled in computer repair.

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.
