Abstract
A system has a fluid motor for receiving a pressurized fluid motor causing actuation of the fluid motor, with the fluid motor having a motor inlet and a motor outlet. The motor fluid is delivered from the motor outlet into a container. The motor rotor drives a pump rotor. The pump rotor drives a fluid from a pump inlet to a pump outlet, with the pump outlet being connected into the container. A metering system allows a precise amount of rotation of the motor rotor and the pump rotor to meter the motor fluid and the pump fluid into the container.
Claims18
A system comprising:
- a fluid motor for receiving a pressurized motor fluid causing actuation of said fluid motor, with said fluid motor having a motor inlet and a motor outlet, and said motor fluid being delivered from said motor outlet into a container, and a motor rotor driving a pump rotor, said pump rotor driving a pump fluid from a pump inlet to a pump outlet, with said pump outlet being connected into said container;
- a metering system for controlling an amount of rotation of said motor rotor and said pump rotor to meter said motor fluid and said pump fluid into said container;
- and
- wherein the metering system includes a meter rotor which rotates with said moter rotor and said pump rotor, and a stop pin for preventing rotation of said meter rotor after the amount of rotation of said motor rotor and said pump rotor.
