Abstract
The present invention provides a shuttle valve for a multipath hydraulic circuit comprising a valve body having a main passage extending along an axis and having a uniform inner periphery. The shuttle valve further has a slider valve positioned within the main passage which has a first section adjacent and attached to a second section. The first section has a first outer periphery substantially similar to the inner periphery of the main passage such that the first section of the slider valve and the main passage substantially prevent fluid flow therebetween. The first outer periphery extends a predetermined length which is shorter than the intersection length. The second section has a second outer periphery with a recessed portion being recessed from the outer periphery of the main passage such that fluid is able to pass between the second section and the inner periphery of the main passage. As a result, fluid is able to pass from the first passage and around the slider valve and to the second passage or the third passage.
