力源システム。[Claims for Utility Model Registration] 1. A compressed air pressure source system for a vehicle that is attached to a vehicle and provides compressed air to the vehicle, which contains a renewable desiccant agent between an inlet and an outlet. an air dryer, an air compressor connected to the inlet for supplying compressed air, an air tank connected to the outlet for storing compressed air dried by the desiccant, and a pressure in the air tank reaching a predetermined upper limit. a governor that outputs an unload signal that disables the operation of the air compressor until the air compressor reaches a predetermined lower limit after reaching a predetermined lower limit value; In a compressed air power source system for a vehicle comprising a drain valve that communicates with the drain valve, the transmission of the unload signal to the drain valve can be operated intermittently in response to a switching operation by a driver when the speed of the vehicle is below a predetermined value. death,
A compressed air pressure source system for a vehicle, comprising a control device that allows transmission of the unload signal to the drain valve regardless of the switching operation when the speed of the vehicle exceeds a predetermined value. 2 A compressed air pressure source system for a vehicle that is attached to a vehicle and provides compressed air to the vehicle, which comprises an air dryer containing a recyclable desiccant between an inlet and an outlet, and an air dryer connected to the inlet. an air compressor for supplying compressed air, an air tank connected to the outlet for storing compressed air dried by the desiccant, and a pressure in the air tank reaching a predetermined upper limit and then decreasing to a predetermined lower limit. a governor that outputs an unload signal that disables the operation of the air compressor until the air compressor decreases; a drain valve that connects the inlet side of the desiccant to the outside of the air dryer upon receiving the unload signal; A compressed air pressure source system for a vehicle comprising a drain tank connected to the inlet side of the desiccant via a valve, wherein the inlet side of the desiccant is isolated from the drain tank and communicated with the atmosphere. a switching valve having a first switching position and a second switching position that blocks the inlet side of the desiccant from the atmosphere and communicates with the drain tank; The switching valve is enabled to switch to each of the switching positions in response to a switching operation, and when the speed of the vehicle exceeds a predetermined value, the switching valve is prohibited from assuming the second switching position regardless of the switching operation. A compressed air pressure source system for vehicles equipped with a control device.
