Abstract
A distribution valve for directing high pressure coolant to various stations of a metalworking machine or similar device. A hollow shaft directs high pressure fluid to an aperture in a seal plate. The aperture is selectively coupled to one of several seals mounted in a housing. Each seal is formed with an axial passageway for directing fluid to its respective station when aligned with the aperture. A biasing means holds the seal against the seal plate to provide a leak free interface.
