An assembly system for components of a pressurized fluid supply system for an agricultural vehicle includes a body having at least one fluid duct connectable at one end to a pressurized fluid supply and having a socket at the other end. A detachable component such as an accumulator or oil filter is connectable in releasable mechanical engagement with the body to receive pressurized fluid from the at least one fluid duct. The engagement results from insertion of at least a portion of the component into the socket and rotation of the component to a locked position. The body has at least one discharge duct extending therethrough. In a partially rotated position of the component portion within the socket, the component remains mechanically attached to the body and the fluid duct and discharge duct are in fluidic connection, discharging accumulated pressure in the fluid duct.

A recycling secondary reservoir of a hydraulic system is charged with clean fluid from a primary hydraulic circuit. The secondary reservoir maintains clean fluid for use by a backup pump to cycle a hydraulic device. The secondary reservoir recaptures fluid used by the backup pump to maintain clean fluid that can be reused an indefinite number of times.

A hydraulic system for an agricultural system includes a hydraulic circuit and a bi-directional filter disposed on a bi-directional fluid line of the hydraulic circuit. The bi-directional filter includes a check valve fluid line having a check valve configured to block a fluid from flowing through the check valve fluid line in a first direction and to enable the fluid to flow through the check valve fluid line in a second direction, opposite the first direction, and a filter fluid line having a filter configured to enable the fluid to flow through the filter fluid line in the first direction and the second direction. The filter is configured to block particles that are greater than a threshold size from passing through the filter fluid line, and the filter fluid line is in a parallel flow configuration with respect to the check valve fluid line.

An arrangement for a utility vehicle includes at least one air dryer unit and a regulating unit, wherein the air dryer unit and the regulating unit are designed in each case as separate units. The air dryer unit has at least one air dryer module, in particular an air dryer cartridge, at least one discharge valve and at least one control line for the pneumatic control of the discharge valve. At least one connecting line is provided in the air dryer unit with connection to the air dryer module. The connecting line leads directly to a consumer non-return valve for the air dryer unit, which is arranged outside of the air dryer unit, wherein the connecting line can be used at least partially bi-directionally and/or can be or is connected to a bi-directionally usable line section.
