Title:
EXHAUST GAS SUCTION FLOW POWER DEVICE
Document Type and Number:
Japanese Patent JP2019074051
Kind Code:
A
Abstract:
To provide an exhaust gas suction flow power device to which appropriate parameters are set in such a manner that optimal achievement can be obtained as an exhaust gas suction flow power device that is connectable to various apparatuses each comprising an internal combustion engine.SOLUTION: An exhaust gas suction flow power device 10 comprises: a device body 20 which is structured cylindrical as a whole; a negative pressure generation part 30 which generates a negative pressure by accelerating an exhaust gas flow flowing in from an exhaust gas flow-in side and flowing the exhaust gas flow out to an exhaust gas flow-out side and is structured cylindrical as a whole; and a high-speed flow receiving tube 50 which is provided at the exhaust gas flow-out side of the device body 20 and structured tubular as a whole in order to emit the exhaust gas flow that is accelerated by the negative pressure generation part 30, into an atmosphere. A cross-sectional area S2 of the negative pressure generation part 30 at the exhaust gas flow-out side is substantially set to 1/4 as large as a cross-sectional area S1 at the exhaust gas flow-in side, and a cross-sectional area S3 and a length L of the high-speed flow receiving tube 50 are set in such a manner that an outer peripheral surface EL of the exhaust gas flow that is accelerated and made flow out of the exhaust gas flow-out side of the negative pressure generation part 30 is abutted to an inner surface of the high-speed flow receiving tube 50.SELECTED DRAWING: Figure 3
