Abstract
An embodiment includes a device that limits the fluid volume that can travel through a hydraulic system or loop before stopping the flow of hydraulic fluid. This can be used to limit the number of rotations/overall movement of a hydraulic motor. It can also be used to create an intermediate position of a hydraulic cylinder between fully extended or retracted. An embodiment enables the direct replacement of a direct acting, piston type actuator with that of a rotary vane motor without reworking the control devices or procedure/training of users/operators. An embodiment can be used to approximate the binary position of a remote actuator without directly monitoring that actuator.
Claims19
A system comprising:
- a hydraulic fluid source;
- a first cylinder including a first piston;
- a first hydraulic fluid line coupling the hydraulic fluid source to the first cylinder, the first hydraulic fluid line including a first hydraulic fluid;
- a rotary hydraulic motor having an output shaft that is an actuator;
- a second hydraulic fluid line coupling the first cylinder to the rotary hydraulic motor, the second hydraulic fluid line including a second hydraulic fluid;
- wherein the first cylinder is located above water and the rotary hydraulic motor is located underwater.
