  • Patent number: 9765708
    Abstract: An altitude fuel limiter and method for controlling an engine using the same is provided. The altitude fuel limiter includes a torque screw sleeve extending from an inboard end to an outboard end. The torque screw sleeve has an interior surface defining a central bore extending axially within the torque screw sleeve. A plunger is disposed within the central bore and moves axially between a first position and a second position. A plunger regulator senses ambient pressure and is coupled with the plunger to axially displace the plunger toward the inboard end of the torque screw sleeve to the first position in response to sensing an ambient pressure that is below a predetermined pressure. The predetermined pressure may be associated with non-compliant altitudes and the plunger limits fuel delivered to the engine when displaced to the first position.

  • Patent number: 5727806
    Abstract: A utility tow bar includes a coupler assembly, a pair of tow arms and fasteners for securing the tow arms to the coupler assembly. More specifically, the coupler assembly includes a tow arm receiving channel for holding the tow arms as well as a hitch ball receiving socket and hitch ball lock for connecting the utility tow bar to a towing vehicle. Preferably the tow arms are substantially S-shaped. Each tow arm is connected at its proximal end to the coupler assembly. Each tow arm includes a connector at its distal end for connecting to a trailing vehicle. Two sets of aligned mounting apertures are provided in the coupler assembly and tow arms. A pair of pull pins are received in the aperture sets to secure the tow arms and coupler assembly together. Pin clips secure the pull pins in position.
