Abstract
A hydraulic drive circuit comprises a source of fluid flow, at least one hydraulic actuator and a rotary flow divider which operates in conjunction with valve means to provide intensified flow to the at least one hydraulic actuator.
Claims5
A fluid power circuit comprising:
- a) a source of fluid flow at a first pressure;
- b) a valve means connected to said source of fluid flow;
- c) a rotary flow divider;
- d) an actuator connected to a fluid outlet of said rotary flow divider;
- wherein said valve means includes a first position wherein substantially all the fluid flow is supplied to the actuator at the first pressure and a second position wherein a first portion of the fluid flow is diverted from said actuator and a remaining portion of said fluid flow is supplied to said actuator at a second pressure, said second pressure higher than said first pressure.
2 more elements
A fluid power circuit comprising:
- a rotary flow divider having an inlet connected to a source of hydraulic fluid under pressurized flow, said rotary flow divider having a first outlet connected to a low pressure means to return fluid to an inlet of said source of hydraulic fluid pump;
- said rotary flow divider including a second outlet connected to a driven circuit;
- said source of hydraulic pressure including a valve having a first position to selectively bypass said rotary flow divider to supply said hydraulic fluid directly to said driven circuit and a second position to supply hydraulic fluid to said rotary flow divider.
