Abstract: An elbow fluid flow valve exhibiting reduced flow loss and including a body having a specified shape and size and defining a short radius associated with an elbow shaped fluid passageway characterized by a first fluid flow inlet and a second fluid flow outlet. A cover secures over the valve body, and such that a generally sleeve shaped annulus is defined therebetween. A light-weight and linearly translatable sleeve is mounted exteriorly of the valve body and within the intermediately defined annulus. The sleeve is operable to be displaced between a first location permitting fluid flow to the outlet and a second location interrupting fluid flow. A control element is operably connected to a pair of access ports, in turn communicated with one or a pair of interior regions in communication with locations of the displaceable sleeve and, upon experiencing at least one of a pressure and flow disparity between valve inlet and outlet, facilitates displacement of the sleeve to the second (flow interrupting) location.

Abstract: A fixed throttle 12 is provided in a delivery line 11a of a fixed pump 11 driven by an engine 9 for rotation together with a hydraulic pump 1, and a differential pressure detecting valve 31 is provided in association with the fixed throttle 12 to detect a differential pressure across the fixed throttle 12 and to output a pressure lower than the detected differential pressure by a predetermined value. The output of the differential pressure detecting valve 31 is introduced, as a signal pressure, to a pressure bearing section 5c of a load sensing valve 5, thereby setting a target differential pressure. With that arrangement, a pressure in link with an engine revolution speed can be directly employed as the set differential pressure of the load sensing valve, and the structure of the load sensing valve can be avoided from being complicated. Further, in the idling revolution range in which the work amount is relatively small, the displacement of the hydraulic pump can be reduced to improve fine operability and cut down fuel consumption.

Abstract: A load sensed variable output gear pump having adjustable high pressure compensation, tuneable response, low unloading pressure and variable pressure drop adjustability. It comprises a unitary housing enclosing a pump which pumps through a main inlet-outlet passage which by-passes through a fixed control and a variable control to an outlet passage leading to a reservoir. An overload control may also be used connected to an inlet load sensing passage which tends to close said fixed and variable controls.

Abstract: A two liquid heat exchange system, and a safety valve to prevent contamination of one liquid (first liquid) by the other. In systems such as hydronic solar systems, it is customary for a first liquid to be heated and run through a heat exchanger where its heat is transferred to a second liquid, often in a storage tank. This invention provides a safety valve which dumps the first liquid in case the pressure of the second liquid does not exceed the pressure of the first liquid by at least a predetermined difference.

Abstract: A hydraulic circuit breaker or fail-safe device is disclosed for sensing leaks in lines to and from hydraulic actuators or the like. Flow through the line is sensed across a restriction on a piston valve member movable to close the line, the size of the restriction being such that flow in excess of normal requirements causes a significantly increased pressure drop, which drop is sensed across a quantity measuring piston movable in a chamber within the piston-valve, and causing the latter piston to move within its chamber at a rate controlled by the area of a control orifice. As this latter piston moves, it carries a shaft which is spring biased to resist movement until the pressure drop across the restriction reaches a value indicative of a leak. Two spool valve members are carried on the shaft whose function in the two embodiments shown is to direct either supply pressure or lower pressure against operating areas of the piston-valve to control its movement to open or close the line. A check valve is placed in a return line and an additional piston in contact with the biasing spring senses a leak in the return line as indicated by a changed pressure drop across the check valve and moves to either remove the effective spring bias on the shaft or to move the shaft directly such that the spool valve members direct flow to cause the piston-valve to close the line.

Abstract: 1,140,581. Heart and lung resuscitators. C. E. HEWSON. 4 Jan., 1966, No. 365/66. Headings A5R and A5T [Also in Division G3] A lung ventilator comprises a duct 69, 70 and a fitting 14 for introducing lung-ventilating gas to a patient, a fixed volume tank 58 for metering the amount of lung-ventilating gas and connected to the duct, means for introducing a controlled amount of lung-ventilating gas into the tank and valve means 60 in the duct for connecting and disconnecting the tank and the fitting, the said introducing means and said valve means being so arranged that gas is introduced to the tank only when the tank is not connected to the fitting. The lung ventilator is combined with a heart resuscitator comprising a pneumatically operated compressor 12 for exerting pressure on the heart and includes a pneumatic circuit for cyclically operating the lung ventilator and the compressor in timed relation to each other. The control means is disposed in a case 22 which is shaped to form a shoulder lift and which includes a combined handle and head support 38. Straps 16 retain the compressor 12 on the patients chest. The device includes a respiratory mask 14. Oxygen from a supply 18 at 90 p.s.i. flows through an 'on-off' valve 48 and a pressure regulator 52, which reduces the pressure to 48-50 p.s.i. to a pneumatically controlled valve 54 which normally connects the supply to a line 70. A pneumatic pulse generating circuit 56 (see Division G3) is then energised and emits gas pulses at its outlet 78 at 60 per min., and the metering tank 58 is filled under the control of an adjustable regulator 82. A pneumatically controlled valve 60 between the tank and the mask is normally closed. The gas pulses are supplied through a pilot line 68 to a valve 62, which opens in response to each pulse, to direct oxygen in a line 50 through a regulator 82' to the cardiac compressor 12. The gas pulses also operate a counter 64 in a pilot circuit 66 to permit the valve 54 to change over so that oxygen is supplied to a pilot line 72 and disconnected from line 70 only once in every five pulses. When oxygen is supplied to the pilot line 72, the valve 60 is opened to connect the tank 58 with the mask. The valve 60 (see Division F2) includes a spool (118, Figure 5) which, as it moves to open the valve, provides a flow path of increasing dimensions so that the gas volume passing to the mask increases gradually at a predetermined rate. As the tank empties or reaches a preselected minimum pressure, pressure in a pilot line 113 closes a normally open valve 111 to change over the valve 54 to connect the oxygen supply to the line 70 and disconnect the line 72.
