Abstract:
A shuttle valve for a multipath hydraulic circuit, said shuttle valve comprising:a valve body having a main passage extending along an axis and having a uniform inner periphery, said valve body having a first passage intersecting said inner periphery of said main passage at a first intersection area, said first intersection area having an intersection length extending parallel to said axis, said valve body having a second passage intersecting said inner periphery of said main passage at a second intersection area, said second intersection area being away from said first intersection area in a direction parallel to said axis, said valve body having a third passage intersecting said inner periphery of said main passage at a third intersection area, said third intersection area being located away from said first intersection area and positioned on an opposite side of said first intersection area from said second intersection area;a slider valve positioned within said main passage, said slider valve having a first section adjacent and attached to a second section, said first section having a first outer periphery substantially similar to said inner periphery of said passage such that said first section of said slider valve and said main passage substantially prevent fluid flow therebetween, said first outer periphery extending a predetermined length parallel to said axis, said predetermined length being shorter than said intersection length of said first intersection area;said second section having a second outer periphery, said second outer periphery having a recessed portion being recessed from said outer periphery of said main passage such that fluid is able to pass between said second section and said inner periphery of said main passage; andwhereby fluid is able to pass from said first passage and around said slider valve and to said second passage or said third passage.
