  • Dual evaporator air conditioner
    Patent number: 4873837
    Abstract: This application concerns an automobile air conditioning system having two evaporators and one compressor which is alternately activated and deactivated to prevent frost from accumulating on one of the evaporators by way of a refrigerant pressure responsive switch at the outlet of the one evaporator. A one-way check valve is located near the switch and between the evaporators to prevent reverse flowing of refrigerant from the one evaporator to the other evaporator.

  • Fuel injection heating system
    Patent number: 4870932
    Abstract: An injector heating apparatus and system for a vehicle engine having fuel injectors with a solenoid coil in a housing for passing fuel into the engine, including an electrical control unit to alternately produce a normal engine run mode and an injector heating mode. A temperature sensing switch signals the electrical control so that in the injector heating mode the fuel pump and engine starter are deenergized and the injector coils are energized for a timed period so that the injectors can be heated and subsequently the temperature of fuel passed therethrough is increased by heat transfer therefrom during a subsequent start and run mode of operation.

  • Pressure transducer with a sealed sensor
    Patent number: 4866989
    Abstract: A transducer for sensing fluid pressure including an enclosure forming housing, a cup-shaped rubber-like mount having an end wall and an annular side wall for supporting a pressure sensing electronic chip against the inner end wall surface of the mount. The chip is supported against the end wall in covering relation to a small opening in the end wall which connects one side of the chip with atmospheric pressure. A layer of non-hardening sealant gel extending between the inner side wall surface completely covers the chip and transmits fluid pressure to a second surface of the chip but inhibits fluid contact and leakage past the chip.

  • Differential pressure fluid level sensor
    Patent number: 4843883
    Abstract: A liquid fluid level sensor responds to differential pressure forces exerted on a diaphragm as produced by exposure of liquid fluid to one side and of atmosphere to the other side. An arched resistance card is movable with the diaphragm to engage the mid-portion of a metal spring which progressively overlies greater portions of the card as the diaphragm moves thereby changing the resistance of a circuit including the card and the spring.

  • Motion transducer
    Patent number: 4806901
    Abstract: A device for transmitting linear motion into rotary motion, particularly as applied to an oil pressure transducer for a vehicle I.C.E. Specifically, the linear movement is produced by action of pressure against a diaphragm as opposed by a yieldable spring. The spring is a wire curved into a helix shape and with the ends attached to a rotary table. The midportion of the spring is operably attached to the central portion of the diaphragm so that linear movement thereof toward the rotary table causes the spring's end portions to progressively engage the table in overlying relation and, accordingly, to produce rotation of the table.
