Abstract
A hydraulic drive with regeneration circuit comprises a pump, a hydraulic actuator and a rotary flow divider which operates in conjunction with valve means to provide regeneration flow for the hydraulic drive.
Claims8
A hydraulic drive with regeneration circuit comprising:
- a) a pump;
- b) at least one hydraulic actuator;
- c) a first valve means;
- and
- d) a rotary flow divider;
- wherein said first valve means comprises a first position and a second position;
- wherein when said first valve means is in said first position, said rotary flow divider is isolated from fluid flowing from said pump;
- and
- wherein when said first valve means is in said second position, fluid flow from the at least one hydraulic actuator flows through said first valve means and through the rotary flow divider, resulting in a portion of the fluid flow from the at least one hydraulic actuator through said rotary flow divider to be returned to a reservoir and another portion of the fluid flow from the at least one hydraulic actuator through the rotary flow divider to be compbined with fluid flow from said pump into said at least one hydraulic actuator.
6 more elements
A hydraulic drive with regeneration circuit comprising:
- a pump taking fluid from a reservoir and providing pressurized fluid flow through a first line to at least one hydraulic actuator;
- said hydraulic actuator having an outlet line connected to a first valve means;
- said first valve means having a first position wherein fluid from said outlet bypasses a rotary flow divider;
- said first valve means having a second position wherein fluid from said outlet flows to said rotary divider;
- said rotary flow divider,returning a first portion of the fluid from said outlet to the reservoir and pressurizing a second portion of said fluid from said outlet and combining it with the fluid flow in said first line.
