Systems and method determine a fluid efficiency of a fluid that flows through a fluid power system. Characteristics of the fluid is monitored in real-time as the fluid flows through the fluid monitoring device that is coupled to the fluid power system as the fluid flows through the fluid power system. A fluid status is determined in real-time that is associated with fluid parameters of the fluid that is determined from the fluid parameters detected by the fluid monitoring device. The fluid status of the fluid is determined in real-time when the fluid status indicates that a corrective action is to be executed to increase a quality of the fluid and an assessment of the corrective action that is to be executed is generated based on the fluid parameters. Degradation of the components of the fluid power system increases without the corrective action being executed to the fluid.

A throttle assembly for a pressure control system in a vehicle includes at least one throttle valve. The at least one throttle valve defines an assembly cross-section of the throttle assembly, the assembly cross-section specifies a flow resistance acting on a pressure medium entering the throttle assembly, and the at least one throttle valve includes at least one controllable throttle valve configured to be controlled in accordance with an upstream pressure. The assembly cross-section of the throttle assembly is configured to be set, by control of the at least one controllable throttle valve, in such a way that an inlet volume flow of the pressure medium entering the throttle assembly can be limited to a limit volume flow in accordance with the upstream pressure, in order to set, in accordance with the upstream pressure, a power consumption of a pneumatic load in the pressure control system.

A resin molded article has an internal space. The resin molded article includes: a ventilation passage defined to allow the internal space to communicate with an outside of the resin molded article. The ventilation passage includes: a first ventilation passage extending from the internal space in a predetermined direction so as to include a bottom portion; and a second ventilation passage extending from the outside in a direction intersecting the predetermined direction. The first ventilation passage and the second ventilation passage communicate with each other by allowing the bottom portion to communicate with the bifurcated portions provided at an end portion of the second ventilation passage. A portion where the first ventilation passage and the second ventilation passage communicate with each other is narrowest in the ventilation passage.

A bypass for an air dryer having an inlet, a prefiltration stage having a drain valve to purge contaminants, a pair of inlet valves in communication with the prefiltration stage to control the flow of compressed air through the desiccant towers, and an outlet coupled to the pair of desiccant towers. The bypass may be a bypass valve that is normally open to the outlet when the air dryer is unpowered and pilotable to be a closed to allow air to flow to the prefiltration stage when the air dryer is powered. The bypass may be a three-way valve that is normally coupled to the outlet and that may be piloted to connect to the prefiltration stage when the dryer is powered. The bypass may also be a check valve that opens in response to pressure in the inlet to allow compressed air to flow directly to the outlet.

Inside a tank body storing a liquid, a return filter is provided protruding downward from an upper surface of the tank body, and a substantially plate-like (plate-shaped) float is also provided that is inserted into the tank body and floats in accordance with change in a liquid surface of the liquid stored in the tank body. The float is provided with an opening larger than a diameter of a filter case, and in a plan view, the float is disposed between the tank body and the filter case.

Transmissions, filter assemblies for transmissions, and valve assemblies for transmissions are disclosed herein. A transmission includes an input shaft, an output shaft, and a hydraulic system. The input shaft is configured to receive rotational power supplied by a drive unit. The output shaft is coupled to the input shaft and configured to provide rotational power supplied to the input shaft to a load. The hydraulic system is configured to supply fluid to one or more fluid demand devices coupled between the input shaft and the output shaft in one or more operating modes of the transmission. The hydraulic system includes a filter assembly having a filter element and a valve assembly fluidly coupled to the filter element.

A gasket device for a pneumatic valve system, in particular of a commercial vehicle, comprises gasket part being adapted to be inserted into at least a groove of a contact face of a first casing part, e.g. an adapter, the gasket part comprising at least one gasket chamber for sealingly connecting device channels of mounted casing parts; a body part being adapted to be received in a valve seat of the casing part; at least one spring part connecting the body part and the gasket part,
wherein the body part is moveable in an airflow direction relative to the gasket part by bending or stretching the at least one spring part,
wherein in an unbiased basic condition of the gasket device the body part is positioned above a gasket plane defined by the gasket chamber.

The gasket device is made as a single part of a flexible, elastic material.

A work vehicle transmission includes a first transmission mechanism that changes input motive power to any one of multiple speeds, and a second transmission mechanism that changes the motive power changed by the first transmission mechanism to any one of multiple speeds, the number of speeds of the second transmission mechanism being smaller than that of the first transmission mechanism. Multiple speed change multi-disc clutches of the first transmission mechanism are arranged parallel with multiple deceleration multi-disc clutches of the second transmission mechanism so as to be adjacent in the diameter direction thereof.
