Abstract:
An inductor pump system comprises a fluid activated ram, an inductor pump platen, a fluid activated motor and a fluid control. The inductor pump platen is driven by the fluid activated ram. The fluid activated motor is coupled to the platen. The fluid control comprises an inlet for receiving a source of pressurized fluid, a first circuit and a second circuit. The first and second circuits are configured to receive pressurized fluid from the inlet. The first circuit comprises a switching valve connected to the inlet; an actuator line connected to the ram and the switching valve; and a blow-off line connected to the inductor pump platen and the switching valve. The second circuit is connected to the inlet to receive pressurized fluid and to the motor.
