Abstract
A hydraulic system for an air cart includes a primary hydraulic assembly and a secondary hydraulic assembly. The hydraulic system also includes a first valve configured to block a flow of a hydraulic fluid flowing in a first direction from the primary hydraulic assembly and a second valve configured to block a flow of the hydraulic fluid flowing in a second direction from the secondary hydraulic assembly.
Claims15
A hydraulic system for an air cart comprising:
- a primary hydraulic assembly comprising a first hydraulic actuator;
- a secondary hydraulic assembly comprising a second hydraulic actuator;
- a direction control valve fluidly coupled to the primary hydraulic assembly and the secondary hydraulic assembly, wherein the direction control valve comprises a first position and a second position;
- a first hydraulic fluid loop configured to circulate a hydraulic fluid in a first direction from the direction control valve to the first hydraulic actuator when the direction control valve is in the first position;
- a second hydraulic fluid loop configured to circulate the hydraulic fluid in a second direction, opposite the first direction, from the direction control valve to the secondary hydraulic actuator when the direction control valve is in the second position;
- a first valve disposed along the first hydraulic fluid loop and configured to block a flow of the hydraulic fluid through the first hydraulic fluid loop when the direction control valve is in the second position;
- and
- a second valve disposed along the second hydraulic fluid loop and configured to block a flow of the hydraulic fluid through the second hydraulic fluid loop when the direction control valve is in the first position.

A hydraulic system for an air cart comprising:
- a first primary hydraulic motor configured to power a fan of the air cart;
- a first secondary hydraulic motor configured to power a conveyor, wherein the conveyor is configured to convey a product into a storage tank of the air cart;
- a direction control valve comprising a first position and a second position, wherein the direction control valve is configured to enable a hydraulic fluid to flow in a first direction from the direction control valve when the direction control valve is in the first position and to enable the hydraulic fluid to flow in a second direction from the direction control valve, opposite the first direction, when the direction control valve is in the second position;
- a first hydraulic fluid loop configured to circulate the hydraulic fluid in the first direction from the direction control valve to the first primary hydraulic motor when the direction control valve is in the first position;
- a second hydraulic fluid loop configured to circulate the hydraulic fluid in the second direction from the direction control valve to the first secondary hydraulic motor when the direction control valve is in the second position;
- a first valve disposed along the first hydraulic fluid loop and configured to facilitate flow of the hydraulic fluid in the first direction from the direction control valve to the first primary hydraulic motor and to block the flow of the hydraulic fluid in the second direction from the direction control valve to the first primary hydraulic motor;
- and
- a second valve disposed along the second hydraulic fluid loop and configured to facilitate flow of the hydraulic fluid in the second direction from the direction control valve to the first secondary hydraulic motor and to block the flow of the hydraulic fluid in the first direction from the direction control valve to the first secondary hydraulic motor.
