Abstract: A filter assembly for a servo valve that includes a first fluid nozzle defining a first fluid passage therethrough between a first fluid inlet and a first fluid outlet and a second fluid nozzle defining a second fluid passage therethrough between a second fluid inlet and a second fluid outlet. The first and second fluid nozzles arranged in end to end abutment with each other to form a tubular fluid nozzle unit in which the first and second fluid inlets are adjacent each other, and the first and second fluid passages align to form a common fluid passage through the tubular fluid nozzle unit. The first fluid outlet is at a first end of the tubular fluid nozzle unit and the second fluid passage being at a second, end of the tubular fluid nozzle unit.

Abstract: A metering valve comprising a solenoid having: a coil mounted on a core; and an armature moveable axially with respect to the core and against a return bias in response to a current in the coil; a variable capacitor having a first plate mounted for movement with the armature and a second plate fixed with respect to the core. The metering valve comprises an electronic feedback loop which is used to adjust the current in the coil based on a feedback signal derived from of the capacitance of the variable capacitor. A reference capacitor may be provided having opposing third and fourth plates at a set separation. A valve body may house the solenoid, the variable capacitor and the reference capacitor.
