An air supply system for a vehicle includes a first system including a first compressor compressing ambient air, a heat exchanger connected to the first compressor to allow compressed air to flow therethrough, and a first condenser connected to the heat exchanger. The air supply system further includes a second system including a second compressor compressing a refrigerant, a second condenser disposed at a rear end of the second compressor, an expansion valve disposed at a rear end of the second compressor, and an evaporator disposed at a rear end of the expansion valve. The second compressor, the second condenser, the expansion valve, and the evaporator of the second system are sequentially connected by a refrigerant flow line, and a refrigerant pipe disposed in the evaporator of the second system and connected to the refrigerant flow line is connected to a refrigerant pipe for a first condenser.

The technology relates to a system for cleating a sensor cover. The system may comprise a wiper comprising a wiper support, a wiper blade, and a sensor cover. The wiper blade may be configured to clear the sensor cover of debris, and the sensor cover may be configured to house one or more sensors. A wiper motor may rotate the wiper and a sensor motor may rotate the sensor cover. The system wiper blade may comprise a first edge attached to the wiper support and a second edge which may be configured to be in contact with the sensor cover. The wiper blade may extend in a corkscrew shape around the wiper support. The wiper motor may be configured to rotate the wiper in a first direction and the sensor motor may be configured to rotate the sensor cover in a second direction opposite the first direction.

A flow path switching device can selectively output fluid supplied from a drive pump from either the first output section or the second output section. The device includes a switching valve configured to, in response to a drop in pressure occurring in either of a first output section or a second output section, switch fluid flow to one of the first output section or the second output section in which the pressure drop did not occur.

A device for cleaning a sensor can include a support structure and a platform assembly. The platform assembly can include a platform structure that includes a set of channels and a raised lip structure that is provided around at least a portion of the perimeter of the platform structure. The raised lip structure includes a set of cavities that is connected to the set of channels and a set of openings to enable air to move from the set of cavities to outside the raised lip structure in a direction towards a center of the platform structure.

The tractor trailer compressed air system with accessories is a mechanical device. The tractor trailer compressed air system with accessories incorporates a housing, an air transport structure, a tractor, and a trailer. The housing contains the air transport structure. The housing mounts on the trailer. The trailer attaches to the tractor. The trailer forms a fluidic connection with the tractor. The trailer forms a fluidic connection with the air transport structure. The tractor transfers compressed air to the trailer. The trailer transfers a portion of the received compressed air to the air transport structure. The air transport structure releases the compressed air as an air flow into the atmosphere. The released air flow is used to blow detritus off of and out of the tractor and the trailer.
