The technology disclosed herein relates to a filter element having a first endcap, a second endcap, and filter media extending between the first endcap and the second endcap. The filter media defines a central opening and is coupled to the first endcap and the second endcap. A filter cover is coupled to the first endcap, and a breather filter is integral to the filter cover. The breather filter defines a first flow face and a second flow face. The filter element defines an airflow pathway from ambient environment through the first flow face and the second flow face.

A hydraulic system includes a first electric machine connected to a first hydraulic machine and a second electric machine connected to a second hydraulic machine. An output side of the second hydraulic machine is connected to an input side of the first hydraulic machine. A hydraulic consumer is hydraulically coupled to an output side of the first hydraulic machine via a supply line and is powered by the first hydraulic machine. A return line hydraulically couples the hydraulic consumer to an input side of the first hydraulic machine. The second hydraulic machine provides a flow of hydraulic fluid to the input side of the first hydraulic machine if a requested flow from the first hydraulic machine exceeds a flow of the return line and recuperates energy if the requested flow from the first hydraulic machine is lower than the flow of the return line.

The present disclosure provides a compressed air processing system of which the operation of supplying compressed air and the regeneration operation can be efficiently controlled by an electronic control unit. In particular, the present disclosure is characterized in that the pressure of a regeneration sequence valve installed in a regeneration line is increased over a set pressure by controlling a valve, which is electronically controlled, to switch, so the opening time of the regeneration line is delayed in comparison to the opening time of an unloader valve, whereby regeneration efficiency is improved.

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 guide element for hydraulic fluid includes a first end surface, a second end surface, and an exterior surface connecting the first end surface to the second end surface. The first end surface includes a first chamfered opening. The second end surface includes a second opening that fluidly communicates with the first opening to define a longitudinal bore that includes a tapered section. The first chamfered opening and the tapered section are configured to guide the hydraulic fluid to facilitate transformation of a turbulent flow of the hydraulic fluid into a laminar flow of the hydraulic fluid.

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 device for reciprocatingly removing and replenishing fluid in circulating system of an hydraulic mechanism that includes at least two processing tanks, at least one air pressure regulator and connector releasably engageable with a pressurized air source, at least one vacuum generator, at least one pressure regulator; and means for removing the fluid from the circulating system at vacuum.

An electric-powered fail-safe actuator for use with a valve, where the actuator stores potential energy for conversion to kinetic energy to close or open the valve to the fail-safe position.
