Abstract: The invention relates to a valve assembly for hydraulic systems which has the excess pressure relief function of opening when the upstream pressure exceeds the downstream pressure by a predetermined amount and the refilling function of opening when the downstream pressure exceeds the upstream pressure by a predetermined amount. Both functions involve forms of spring load valves and although one such valve is entirely contained within the other, the flow cross sections are substantially the same or at least have the same order of magnitude. The valve assembly includes an axially movable valve body which forms four pressure chambers with the casing and has four pressure faces to effect axial biasing of the valve body when subjected to fluid pressure in the pressure chambers. Restrictors are used to obtain desired pressures in two of the pressure chambers.

Abstract: The invention relates to a pneumatic pressure regulating assembly. The assembly includes a cylindrically shaped housing having a top or cover portion with holes therein. A spindle member extends through and above the housing with the spindle portion above the housing being hollow and having an inlet opening in fluid communication with the hollow interior. A dish shaped member having a central opening is slidably mounted on the spindle member. The dish shaped member has a flange engageable with the top portion of the housing and being in surrounding relation to the holes in the cover portion. The dish shaped member is raisable by air flowing through the housing and the holes in the cover thereof so as to allow a portion of this air to be blown off and the remaining portion of the air to enter the inlet opening of the spindle member. The dish shaped member has a predetermined weight and the pressure is regulated by reason of the dish shaped member assuming different vertical positions which keeps the pressure constant by varying the amount of air blown off.

Abstract: A measuring transducer circuit arrangement comprises a bridge circuit across one diagonal of which the transducer and a measuring amplifier are connected, and the other diagonal of which has a current regulator connected to one terminal adjacent to a compensating resistor in the bridge and a further resistor connected to the other terminal. The current regulator is controlled in dependence on the voltage across the further resistor to maintain this voltage constant.

Abstract: The invention relates to a converter for measured quantities comprising at least one measuring resistance provided in a compensating bridge, the signal current for restoring the bridge balance being fed through a part of the fixed resistances of the bridge. The output that is required for operation is derived from the supervising current. The bridge is connected in series with a control element which varies the voltage across the bridge in such a way that the sum of the currents flowing through the entire bridge is substantially constant, the voltage drop at one of the fixed bridge resistances being used to form a control signal for influencing the control element. In a preferred form of the invention the bridge comprises first and second branches connected to a feed point with each branch consisting of a fixed resistance serving to form the control signal. A third branch comprises a fixed resistance with a tap for connecting the current path for the signal current and the first branch comprises at least one measuring resistance. This results in a very simply constructed bridge which, in the extreme case, makes do with four bridge elements which are two fixed resistances, a fixed resistance with a tap and a measuring resistance.

Abstract: The invention relates to a metering type control unit for a power steering system. Units of this type most commonly utilize gerotor type gear sets for the metering operation. A problem with this unit is that highly pressurized fluid leaks from the expansible chambers formed between the star and ring members of the gerotor to the central bore of the star. Control units of this type require a universal drive between the rotatable valve thereof and the star which has a combination rotating and orbiting movement. In this invention the universal drive has a sealing flange associated therewith which serves to enclose the central bore of the star so that a fluid tight chamber is formed. Fluid is trapped in this central bore with the result that the pressure differential between the expansible chambers and this central bore is minimized and leakage is consequently minimized.

Abstract: The invention relates to a gerotor type rotary piston machine. The casing has a main axis and the gerotor gear set includes an externally toothed star member which is rotatable about its own axis and orbital about the casing main axis. A main drive shaft is rotatable about the casing axis and a universal type wobble shaft connects the main shaft to the gerotor star member. An annularly shaped valve is mounted in said casing for rotation about the casing main axis. The valve is in surrounding relation to the wobble shaft and is axially positioned between the two ends of the wobble shaft. The wobble shaft has a cross bore and a diametrically extending drive member attached to the valve extending through the cross bore. The wobble shaft has a longitudinally extending bore and a keying shaft having a stem in this bore engages the valve drive member in driving relation thereto. The keying member is needed because the wobble shaft has a compound rotating and orbiting motion whereas the valve only has a rotating motion and something more than a simple shaft and bore connection between them is required.

Abstract: The invention relates to a device for holding and contacting thermally loaded ceramic resistors. Thermally loaded ceramic resistors such as PTC resistors are generally brittle and, while they have the characteristic of a substantial temperature expansion coefficient, they are relatively weak structurally. The device hereof which accommodates a PTC resistor includes resiliently biased electrical contacts which old the resistor firmly in a fixed position while permitting the resistor to expand freely upon being heated without incurring stresses wihch would cause breakage.

Abstract: The invention relates to a control valve assembly for a hydrostatic control system such as a power steering assembly. A common control valve assembly of this type has relatively rotatable inner and outer elements connected respectively to a vehicle steering wheel and a servomotor. Paired holes in the inner and outer elements permit the flow of fluid therethrough when the unit is in its neutral position with the paired holes in respective registration. In prior art units disturbing vibrations occur during the transition from the neutral position to a working position when the paired holes are moved out of registration. These vibrations are eliminated by making the holes in the outer element of varying size and larger than the corresponding holes in the inner element so that a gradual or progressive reduction of the porting area takes place instead of the paired holes closing simultaneously.

Also, a chamber having a flow restricting orifice is incorporated downstream from the holes of the inner element. This provides a sound absorbing system by means of which disturbing noises can be greatly reduced.
