Abstract: An air compression device includes a rotary compressor, a discharge flow channel, a release flow channel and an operation control unit. The discharge flow channel is connected to a discharge portion of the rotary compressor. The release flow channel is disposed to be connectable to the discharge flow channel. The operation control unit is configured to perform a release operation of releasing a part or all of compressed air remaining in the discharge flow channel through the release flow channel when the operation control unit controls to stop the rotary compressor.

Abstract: An air compressor unit for vehicle (2) includes an air compressor (13) for compressing sucked air, an electric motor (14) for driving the air compressor (13), an after-cooler (17) for cooling compressed air generated in the air compressor (13) and an after-cooler cooling fan (18) for generating cooling air for the after-cooler (17) by being driven by a drive force of the electric motor (14). The air compressor (13) and the electric motor (14) are arranged one above the other.

Abstract: The present application discloses an air compression apparatus mounted on a vehicle. The air compression apparatus includes a first air compressor configured to generate first compressed air, a first cooling fan configured to send first cooling wind in a first direction to cool the first air compressor, and a second air compressor aligned with the first air compressor in a second direction intersecting with the first direction. The second air compressor generates second compressed air.

Abstract: The present application discloses a dehumidifying device including a base configured to define an inlet channel for first air flow, and an outlet channel for second air flow less humid than the first; and a first dehumidifier including a first inlet and outlet in communication with the inlet and outlet channel, and configured to dehumidify the first air between the first inlet and the first outlet to generate the second air. The base includes a first base portion configured to define first inlet and outlet regions for the first and second air flows; and a second base portion configured to define second inlet and outlet regions in communication with the first inlet and outlet regions. The first and second inlet regions form at least a part of the inlet channel. The first and second outlet regions form at least a part of the outlet channel.

Abstract: The present application discloses an air compression device, including a housing in which an air compressor is stored, the air compressor being configured to generate compressed air; and a filter through which air passes, the air being sucked into the housing. The filter may include a plate member having a first main plate portion provided with air holes through which the air passes. A surface of the first main plate portion is oriented in a first direction, the air holes extending through the plate member in a second direction intersecting with the first direction so as to change a flow direction of the air.
