  • Patent number: 8696393
    Abstract: The thruster pod that is made of a pump plate; a valve plate affixed to the pump plate, and a diaphragm mounted between the pump plate and the valve plate. The pump plate has juxtaposed pressure cavity and outlet cavity, and a partition separating the pressure cavity from the outlet cavity. The pressure cavity communicates with a source of water under pressure and the outlet cavity communicates with an outlet port. The valve plate has a control chamber facing the juxtaposed pressure and outlet cavities. The diaphragm is mounted between the juxtaposed pressure and outlet cavities and the control chamber for movement between a first position and a second position upon a change in pressure in the control chamber. A control valve is mounted in the valve plate for selectively changing a pressure in the control chamber and operating a diaphragm valve.
