Abstract
A hydraulic system for a work vehicle has a first hydraulic circuit at a first nominal pressure and a second hydraulic circuit at a second nominal pressure different than the first nominal pressure. A dual-chamber hydraulic reservoir includes a first tank associated with the first hydraulic circuit and defining a first opening and a second tank associated with the second hydraulic circuit and defining a second opening. An exchange system has a particulate filter disposed within an exchange path between the first opening of the first tank and the second opening of the second tank. The exchange system is configured to resupply the first tank with hydraulic fluid from the second tank.

A hydraulic system for a work vehicle comprising:
- a first hydraulic circuit at a first nominal pressure;
- a second hydraulic circuit at a second nominal pressure different than the first nominal pressure;
- a dual-chamber hydraulic reservoir including a first tank associated with the first hydraulic circuit and defining a first opening and a second tank associated with the second hydraulic circuit and defining a second opening;
- and
- an exchange system including a particulate filter disposed within an exchange path between the first opening of the first tank and the second opening of the second tank;
- wherein the exchange system is configured to resupply the first tank with hydraulic fluid from the second tank.
A hydraulic system for a work vehicle comprising:
- a high pressure hydraulic circuit;
- a low pressure hydraulic circuit relative to the high pressure hydraulic circuit;
- a dual-chamber hydraulic reservoir including a first tank associated with the high pressure hydraulic circuit and defining a first opening and a second tank associated with the low pressure hydraulic circuit and defining a second opening;
- and
- an exchange system including a particulate filter disposed within an exchange path between the first opening of the first tank and the second opening of the second tank;
- wherein the exchange system is configured to resupply the first tank with hydraulic fluid from the second tank.
