  • Fuel pump with internal pressure regulation
    Patent number: 7134424
    Abstract: An apparatus for delivering fuel includes a fuel pump having a fuel inlet side and a fuel outlet side, and a fuel pumping mechanism operable to draw fuel from the fuel inlet side and pressurize the fuel for transmission to the fuel outlet side. A pressure regulator relieves pressure in the fuel outlet side when such pressure exceeds a predetermined maximum pressure. The pressure regulator includes a by-pass valve, a first fuel port between the fuel outlet side and the by-pass valve, and a second fuel port between the by-pass valve and the fuel inlet side. The by-pass valve is operative, in response to a pressure in the fuel outlet side in excess of the predetermined maximum pressure, to fluidly connect the first and second ports for the return of at least a portion of the fuel from the fuel outlet side to the fuel inlet side.

  • Convertible power top control system
    Patent number: 6630807
    Abstract: A method and system of controlling a movable body portion of a vehicle where the body portion is moved by a motor responding to a control input. Power is applied to the motor upon actuation of the control input and a timer is maintained concurrent with the application of power. Power is removed from the motor as a function of expiration of the timer or relinquishment of the control input. The timer provides a maximum amount of time that power may be applied to the motor, thereby preventing damage to the movable body portion in the event it becomes jammed while being moved by the motor.
