Abstract
A hydraulic brake valve comprising a body, a passageway defined in the body, an inlet to the passageway, an outlet from the passageway and a movable valve member in the passageway, the valve member is movable between a first position blocking the passageway to prevent communication between the inlet and the outlet, and a second position opening the passageway to allow communication between the inlet and the outlet in response to a pressure differential exceeding a predetermined value. The valve member remains in its second position once it has been moved to its second position.
