Three-way hydraulic valve with a floating bushing
Abstract:
An example valve includes: a housing having a first longitudinal cavity therein; a sleeve disposed, at least partially, in the first longitudinal cavity, where the sleeve has a second longitudinal cavity therein, and includes a first seat formed as a protrusion from an interior peripheral surface of the sleeve; a poppet mounted within the second longitudinal cavity and configured to move axially therein; and a bushing mounted, at least partially, in the second longitudinal cavity, such that the bushing is floating and is allowed to move axially in the second longitudinal cavity, where the bushing is hollow and defines a first port at a distal end of the bushing and defines a second seat at a proximal end of the bushing, and where the sleeve defines a second port and a third port disposed on an exterior peripheral surface of the sleeve.
