  • Patent number: 11204134
    Abstract: A secondary indicator for a vapor recovery valve is presented. The vapor recovery valve comprises a piston and a primary indicator, the primary indicator is attached to the piston, and the piston moves linearly in relation to the actuation of the valve and moves proportionally in conjunction with the piston to provide a visual indication that the valve has actuated. The secondary indicator is mounted to the vapor recovery valve and is not attached to the primary indicator. The secondary indicator comprises a signal, a torsional spring, and a fixed pin. The secondary indicator is second class lever, the torsional spring is the effort, the fixed pin is the fulcrum, and the primary indicator is the load between the torsional spring and the fixed pin, such that the signal rotates with the linear movement of the primary indicator to multiply the effect of the primary indicator.

  • Publication number: 20200362968
    Abstract: A seal for a valve stem comprises an upper gland, a lower gland, a packing nut and an accordion type seal that further comprises a seal body that has a plurality of convolutions that are compressible when pressure is applied to the seal body, and an energizer mounted in the interior or exterior root of at least one convolution. The accordion type seal is positioned between the upper gland and the lower gland and the packing nut is threaded onto the valve stem to compress the accordion type seal between the upper gland and the lower gland.

  • Patent number: 6178668
    Abstract: A modular implement apparatus and method of use for securing a snowblower to an all terrain vehicle (ATV) comprises an implement mounted to a first end of the ATV and an engine mounted at a second end. A longitudinal support structure extends between the two ends and supports a drive shaft assembly. The engine provides power to the implement, thus eliminating the need for a PTO shaft. The apparatus is further adapted to permit placement of the apparatus in either a ground-engaging position or a raised, transport position.
