摘要： A pressure differential bypass sensor switch with thermal lockout that utilizes change in position of a permanent magnet carried by a reciprocable piston responsive to pressure differential in a fluid system to actuate a magnetically actuatable electrical switch. Opposite sides of the reciprocable piston are exposed, respectively, to high pressure and low pressure sides of a filter located in a fluid circulating system. The reciprocable piston is normally positioned at the high pressure side of a passage in which it reciprocates, due to biasing by a spring acting on it from the low pressure side of the passage. As the filter becomes clogged, the pressure differential across it and, therefore, across the reciprocable piston will increase. The bypass sensor is calibrated so that a maximum allowable pressure differential in the fluid system will drive the reciprocable piston to the low pressure side of the passage. This movement of the reciprocable piston will carry the permanent magnet to a position relative to the magnetically actuatable electrical switch in which the magnetic field thereof will cause the magnetically actuatable electrical switch to actuate, thereby providing a warning signal indicating an impending filter bypass operating condition. A thermal ferrite is provided adjacent the permanent magnet. The thermal ferrite is selected to have a Curie temperature corresponding to the temperature below which fluid viscosity in the fluid system is high. In the event the reciprocable piston moves due to a pressure differential attributable to high fluid viscosity because of operation below the Curie temperature, the thermal ferrite will act to regionally confine the magnetic field of the permanent magnet, resulting in no actuation of the magnetically actuatable electrical switch.

摘要： An earth-moving machine has an automatic device for minimizing the running speed of the main engine when no power is required by the hydraulic actuators. This device establishes a predetermined hydraulic fluid flow-rate in the servocontrol in the non-neutral position of the servocontrol itself. This flow-rate is indicated by an on-off flow-rate sensor inserted in the auxiliary hydraulic control circuit between the pump and the servocontrols, this sensor controlling the variation in the operating condition of the injection pump of the main engine by means of an electromagnet.

摘要： There is provided a hydraulic pressure operated electrical switch having a spring biased piston which is movable by the force of the hydraulic pressure of the fluid to be sensed to activate a microswitch. The pressure required to move the piston can be altered by adjusting the force produced by the spring acting on the piston. An operating pressure differential is provided by a diaphragm which operates to move the piston by reason of the hydraulic pressure exerted thereon. The diaphragm has a spring rate and produces a force in conjunction with the spring bias against the piston when the piston is moved as a result of the hydraulic pressure overcoming the spring bias. The spring rate of the diaphragm is affected by the amount of hydraulic pressure exerted thereon so that, as a result of adjusting the operating pressure of the switch, the operating differential pressure is altered.

摘要： A pressure sensor probe has a first port connectable to a relatively low pressure source in a compressor crankcase and a second port connectable to a relatively high pressure source at the output of an oil pump. A shuttle is slidably disposed in a bore and has a first end which closes the first port when the difference in pressure between the two ports indicative of normal operation exceeds a selected value determined by the relative areas of the shuttle exposed to the respective pressures and by a coil spring which biases the shuttle away from the first port. A passage is formed between the shuttle and the bore leading from the second port to a force receiving surface on the high pressure side of the shuttle. The length and cross sectional area of the passage is selected to provide a desired dampening or time delay between the high pressure source and the force receiving surface. A control circuit includes a reed switch whose state of actuation is dependent upon the position of the shuttle. The control circuit processes the input signal from the reed switch to control the energization of the compressor motor.

摘要： In an electric circuit interrupter actuator which utilizes gas generator chambers to activate a power cylinder to provide opening and closing of the interrupter, an improved dynamic seal is provided. Such seal works in the reverse direction of an obturator of, for example, a machine gun or artillery piece in that a slidable spring biased sealing ring is provided in the input port to the power cylinder which successively seals with the gas generator chambers which are rotated by it. In order to overcome the friction forces of the initial high velocity gas flow which would otherwise force the ring out of sealing contact, a spring washer is provided having sufficient force to overcome this initial friction force. Thereafter, the high pressure gas exerts a force on the end of the ring in a direction opposite the gas flow to force the sealing ring into tighter engagement. Also, the natural circumferential expansion of the sealing ring, due to the high pressure, promotes radial sealing.

摘要： A fluid pressure switch includes a housing with a cylindrical bore, a spring housing bore and a guide bore between the cylindrical bore and the spring housing bore. A shaft member axially disposed in the housing between the bore, has a piston element secured on the end within the cylindrical bore for movement in one direction or another upon a differential between fluid pressure sources as presented to the two opposing surfaces of the piston element. A spring-biasing arrangement is secured to the shaft member on the end within the spring housing bore for opposing movement of the shaft member. The spring-biasing arrangement is adjustable both as to the spring force and as to the spring stop setting. A switch operator member secured to the piston member, spreads contact arms apart upon a predetermined displacement of the piston. The switch operator member has an elliptically-shaped eccentric portion which can be rotated to adjust the point of shaft displacement at which switch operation occurs.

摘要： A differential pressure switch is disclosed. The switch functions through a conductive path formed within the fluid of a single cavity of a housing having passages for communicating high and low pressure fluid to the cavity. The switch has a cantilevered post with movable conducting and nonconducting members mounted thereabout and being movable between conductive and nonconductive states according to the differential pressure within the cavity. One of the movable members provides sealing between the post and the cavity wall to separate the high and low pressure fluids.

摘要： A pressure switch device having a fire resistant welded assembly of corrosion resistant steel components exposed to the fluid medium which is being monitored. A flexible diaphragm constructed of corrosion resistant steel film is overlaid by a backing disc and backing ring both formed of corrosion resistant steel. Inside the backing ring is an elastomer disc which receives a stainless steel piston that moves up and down in response to changes in the fluid pressure applied to the diaphragm through a pressure port. The piston has a shaft which actuates an electrical switch in response to changes in the pressure of the fluid medium. The periphery of the diaphragm is secured by a pressure tight weld to the housing, the upper corrosion resistant steel disc and the backing ring to provide a fire resistant assembly which confines the pressure medium in the event of a fire.
