Title: Fuel tank filler neck cap
Inventor: HARRIS ROBERT S
IPC: B60K15/04
Filed: 1982-06-15
Granted: 1986-10-09
Abstract: A cap for a filler neck of a fuel tank has a pressure/vacuum valve assembly (32) which comprises a pressure-release valve (40), a vacuum-relief valve (52), and a pressure-release control member (70) in a vent passageway (31) in the cap. A control spring (80) urges the pressure-release valve (40) normally to close and seal the vent passageway (31) and urges the pressure-release control member (70) to form a restricted opening for the flow of fuel vapor. The pressure-release valve (40) is urged in opposition to the control spring (80) to open the vent passageway in response to a predetermined superatmospheric pressure and allow fuel vapor to flow in the restricted opening. A relatively small increase in pressure in the restricted opening produces a large force against surfaces of both the pressure-release valve (40) and the pressure-release control member (70) in opposition to the control spring (80) rapidly to increase the flow of fuel vapor through the vent passageway.

Filed: 1982-12-30
Granted: 1988-06-09
Abstract: The tubular, pneumo-dynamic bearing includes two concentrically-bonded tubes (42,44) which act as a transducer (41). One of the tubes is electro-restrictive. The tubes are disposed in a supporting relationship to at least one of two tubular members which form juxtaposed bearing surfaces. One of the transducer tubes is shorter than the other to lower the weight of the bearing. This also reduces tilting of the tubular bearing members on a shaft.

Abstract: An internal combustion engine may be driven in the suction mode as well as the supercharging mode. Switchover from the suction to the supercharging mode takes place with the accelerator pedal in a switchover position, and switchback to the suction mode is effected in the return switching position of the accelerator pedal. The switchover and switchback positions are offset with respect to each other with the accelerator pedal in a central position between its initial position and its final position. The arrangement is such that the switchover position is reached at the end of the suction mode at fully open throttle flap (full power position). Upon switchover the throttling of the supercharging flow (throttling begin position) is increased as compared to the end of the suction mode. This throttling of the supercharging is diminished by further actuation of the accelerator pedal in the direction of the final position. Corresponding switchback from the supercharging to the suction mode takes place when the accelerator pedal is in the switchback position at which the drive of the supercharger established by the engine shaft is interrupted and a change is made from the stronger throttling during the supercharging mode to the weaker throttling in the suction mode.
