Abstract: A cleaning apparatus includes a fluid discharge portion discharging fluid to a cleaning object, a gas discharge portion jetting gas to the cleaning object, a fluid tank, a fluid pump supplying the fluid via a fluid passage, a gas pump supplying gas via a gas passage, a control unit, a housing at which a part of the fluid passage and a part of the gas passage are provided, and a valve element switchable between a closed position at which the gas passage is blocked and an open position at which the gas passage is opened, the valve element including a first surface receiving a fluid pressure in a direction where the valve element is brought to the closed position and including a second surface receiving a gas pressure in a direction where the valve element is brought to the open position in a state where the valve element is closed.

Abstract: A housing includes an air introduction flow passage, an air discharge flow passage, and a desiccant agent accommodated in the housing. One end portion of the housing is at a lower side of the housing in a vertical direction aligned with the axial direction. An air-liquid separation chamber is formed at a bottom portion of the housing, and includes an air supply passage supplying air to the desiccant agent at an upper housing surface, and is communicated with the air introduction flow passage and the air discharge flow passage to separate moisture in the air introduced from the air introduction flow passage. An adsorption member is accommodated in the air-liquid separation chamber to adsorb moisture separated in the air-liquid separation chamber. Air introduced from the air introduction flow passage is supplied to an air suspension device through the adsorption member and the desiccant agent.

Abstract: An air suspension system is provided with air spring devices, a pressure accumulation tank, a compressor device that supplies compressed air at least to the pressure accumulation tank, and that includes an electric motor, a pump device, and a dryer, and a control device that performs a vehicle height increase control, a vehicle height decrease control, an air suction control, and a regeneration air discharge control. The control device performs a heat accumulation control, by actuating the pump device with the communication between the compressor device and the air spring devices being blocked, supplying the compressed air discharged through the dryer to the pump device to be circulated, and accumulating heat of compression of the compressed air in the dryer, to regenerate the dryer.

Abstract: A flow path switching valve includes a case, a fluid supply portion, a valve body including a first flow portion and a first opposed surface, a second opposed surface provided at the case, a biasing member, a drive portion, a plurality of second flow portions provided at the second opposed surface, and a plurality of fluid discharge portions communicating with the second flow portions respectively, the fluid supply portion being provided to open to a portion in the inner void, the portion being arranged opposite to the first opposed surface relative to the valve body, the first flow portion including a recess portion provided at the first opposed surface to open towards the second opposed surface, the first flow portion including a communication portion provided at the recess portion as viewed in a direction orthogonal to the first opposed surface to communicate between the recess portion and the inner void.
