  • Patent number: 5860233
    Abstract: Construction machines typically utilize hydraulic cylinders to manipulate the linkage that extends between the machine frame and a work implement. In many instances the range of motion of the components creates limited room between the components when they are in their maximum positions. This limited room has prevented the direct attachment of valves to the various hydraulic cylinders. The present invention provides a valve that has a preselected angled configuration that substantially matches a preselected angled configuration of a surrounding frame member. When the linkage is in one of its extreme positions, the two preselected configurations of the valve and the frame member "nest" with one another to prevent contact therebetween, thus allowing the use of the available space.
