Hydraulic control circuit with regeneration valve

摘要

A hydraulic circuit for controlling a component of a hydraulic machine includes an actuator having a head end chamber and a rod end chamber, the actuator having an extended position for moving the component in a first direction and a retracted position for moving the component in a second direction. The hydraulic circuit includes a regeneration valve having an open position for fluidly connecting the head end chamber to the rod end chamber, a first control valve having a first open position, a second open position for fluidly connecting the regeneration valve to the return tank and substantially fluidly disconnecting the rod end chamber from the fluid source, and a closed position, and a second control valve having a first open position, a second open position, and a closed position for substantially fluidly disconnecting the rod end chamber from the fluid source.

1. A hydraulic circuit for controlling a component of a hydraulic machine, the hydraulic circuit comprising:
an actuator having a head end chamber and a rod end chamber, the actuator having an extended position for moving the component in a first direction and a retracted position for moving the component in a second direction; a regeneration valve having an open position for fluidly connecting the head end chamber to the rod end chamber and a closed position for fluidly disconnecting the head end chamber and the rod end chamber; a first control valve having a first open position for fluidly connecting the head end chamber to a fluid source and fluidly connecting the rod end chamber to a return tank, a second open position for fluidly connecting the head end chamber and the regeneration valve to the return tank and fluidly disconnecting the rod end chamber from the fluid source, and a closed position for fluidly disconnecting the rod end chamber from the fluid source and the return tank; and a second control valve having a first open position for fluidly connecting the head end chamber to the fluid source and fluidly connecting the rod end chamber to the return tank, a second open position for fluidly connecting the rod end chamber to the fluid source and the head end chamber to the return tank, and a closed position for fluidly disconnecting the rod end chamber from the fluid source and the return tank.
