摘要： A fuel supply system for an automotive engine has a thermal control regulating choke valve movement in a carburetor to provide smooth engine starting at various ambient temperatures while achieving improved fuel efficiency and pollution emission control. Motion transfer means in the control include cam, cam follower and gear means which are arranged between an electrically-heated, thermally-responsive spring and an additional spring to adapt the control to meet the performance requirements of a particular carburetor or engine. Movement of the thermally-responsive spring in response to temperature change moves the additional spring to provide any linear or non-linear changes in choke valve biasing force which may be desired for improving engine performance during engine warm up.

摘要： A liquid level sensing switch has an open ended chamber in an electrically conductive body, has an insulating bushing disposed in the open end of the body chamber and has a contact member extending through the bushing to dispose one end of the contact member in spaced relation to the body at the closed end of the body chamber. An electrically conductive magnetizable ball is disposed in the chamber for movement between a closed circuit position engaging both the body and the contact member and an open circuit position spaced from one of these components. A float is mounted on the body exteriorily of the chamber and carries a magnet so that movement of the float between two positions outside the body in response to change in liquid level is effective to move the ball between open and closed circuit positions within the body chamber.

摘要： A pressure sensor particularly for measuring pressure within a diesel fuel pump comprises a screw-threaded bolt having a head and a shank and having a bore extending through the bolt through the head and shank. A transducer comprising a piezoelement is disposed in the bore, an electrical terminal extends from the bore through the head of the bolt, an electrical insulator is disposed between the transducer and bore, a threaded element positions one side of the transducer in the bore against the terminal, a spring in the bore extends from the shank end of the bore to bear against the opposite side of the transducer, and an incompressible material surrounds the spring in the bore to transmit a pressure force from a fluid pressure zone in the pump through the shank end of the bore to the transducer to provide a signal from the transducer representative of the pressure in the zone.

摘要： A fuel supply system for an automotive engine has a heater which is energized, deenergized and then reenergized in sequence to heat a thermostat metal coil spring over a selected temperature range to regulate opening of a carburetor choke during engine warm up. The heater operation causes the choke to start to open quickly to enhance fuel economy, then to open more slowly to enhance engine driveability as engine warm up occurs, and finally to complete opening in a rapid fashion to enhance fuel economy when engine driveability is assured after engine warm up has taken place. Contacts are connected between a power source and the heater and a pair of dished bimetal elements having central apertures therein are arranged in facing relation to each other between the contacts, the bimetal elements being adapted to move to inverted dished configuration as they are heated to respective different temperatures within the noted temperature range. The contacts are engaged with each other through the element apertures when engine operation is initiated, are separated when one of the elements moves to its inverted configuration in response to heating of the element, and are then reengaged as the second element moves to its inverted configuration in response to further heating.

摘要： A port fitting is formed with a closed, pedestal end forming a diaphragm on which a strain gauge sensor is mounted. A support member is received on the pedestal end and is formed with a flat end wall having an aperture aligned with the sensor. A portion of a flexible circuit assembly is bonded to the flat end wall with a connector disposed over the support member. A tubular outer housing is fitted over the several components and its bottom portion is welded to the port fitting while its top portion places a selected load on an O-ring received about the connector as well as internal components of the transducer. In one embodiment, a loading washer (72a) is disposed over the O-ring on a first portion (70a) of a two portion connector (70) and retained by a second connector portion (70b). Protrusions (76a1) formed on the tubular housing (76) pass through cut-outs in the second connector portion to place a load on the loading washer. To facilitate assembly, the connector is attachable to the support member in one embodiment by legs of an EMC shield (74), with the shield coupled to the connector by wedging tabs (74c6) and in another embodiment by direct engagement of legs of the connector. In one embodiment a shroud (92) is removably received on the connector to protect elongated terminals extending therefrom. One embodiment is provided with an enhanced environmental seal including a resilient grommet (112) retained by a snap cap (114).
