  • Patent number: 11724222
    Abstract: One or more techniques and/or systems are disclosed for a vehicle fluid filter head. The filter head can be attached to two or more filters to filter vehicle fluid, and provide a variety of optional arrangements for coupling inlet and outlet hoses. A plurality of inlets and outlets can be disposed on the filter head at different sides of the filter head. A pair of filter headers can be disposed on a first side to receive filter. A first inlet and outlet can be disposed on a second side, and a second inlet and outlet can be disposed on a third side. Respective inlet are fluidly coupled with an inlet passage in the head, which is fluidly coupled with an intake portion of the filter headers. Respective outlets are fluidly coupled with an outlet passage in the head, which is fluidly coupled with an outflow portion of the filter headers.
    Type: Grant

  • Patent number: 9788471
    Abstract: A link assembly for a hitch includes a first link and a second link. The second link has first and second spaced apart bores extending therethrough. A coupling member is attached to an end of the first link. The coupling member includes first and second spaced apart coupling plates. The coupling member has a load bore extending through the first and second coupling plates and has a plurality of index bores extending through the first and second coupling plates. A load pin is receivable by the load bore and the first bore, and pivotally couples the second link to the first link. An index pin is removably receivable by the second bore and a selected index bore, and the index pin is movable independently of the load pin.

  • Patent number: 8807312
    Abstract: A hydraulic actuating pin system is disclosed with an actuating pin, clutch drum, spring and hydraulics. The clutch drum has a scalloped annulus with raised and lowered sections. The spring pushes the pin towards the scalloped annulus. When the pin extends into the lowered section, it prevents the clutch drum from rotating. The hydraulics can compress the spring and extract the pin to allow the clutch drum to rotate. The proximal end of the pin can include a head, and hydraulic pressure can move the head to compress the spring. When the pin is fully extended into the lowered section, the end of the pin can not touch the bottom of the lowered section. The hydraulics can include a one-way valve allowing flow from a pump source to the pin, and a pressure release orifice allowing controlled release of hydraulic pressure from the pin.
