Abstract

The invention discloses an adjustable constant-pressure gas inlet device for a rotor engine, relates to pressure adjusting auxiliary equipment for micro rotor engines and belongs to the field of engines. The adjustable constant-pressure gas inlet device comprises a valve, a first plunger, a spring, a second plunger, a third plunger, a fourth plunger, a first work cavity, a first gas outlet, a carburetor, a rotor engine body, a controller, a pressure sensor, a second gas outlet, a check valve, a blast blower, a first gas inlet channel, a second plunger rod, a second work cavity, a first plunger rod, a connection device and a second gas inlet channel. According to the performance of the engine, the pressure in the work cavities can be adjusted precisely in time through mechanical and control combination, so that pressure fluctuation is reduced. The pressure of a gas inlet source is further set through feedback, thus the gas inlet pressure of the blast blower and the pressure of the work cavities are kept consistent, and energy waste is reduced. The gas inlet pressure is further made to be larger than the exhaust pressure, exhausted waste gas is prevented from rushing into the gas inlet channels, and the residual waste gas coefficient is lowered. The adjustable constant-pressure gas inlet device is simple in pressure adjusting operation and sensitive in response.

Description

technical field [0001] The invention relates to auxiliary equipment for micro-rotor engines, in particular to an adjustable constant-pressure air intake device for micro-miniature rotor engines, which belongs to the field of engines. Background technique [0002] With the development of micro-electro-mechanical systems (MEMS) and the introduction of a variety of miniaturized military equipment concepts, the development of micro-energy systems with small volume, light weight, high energy density, and continuous operation has become the focus of attention of various countries. Compared with conventional portable power sources, micro-engines use hydrocarbons as fuels, which have much higher energy density, stable voltage, and low cost. Therefore, micro-engines will have wide application prospects in electronic devices in various industries such as industry, agriculture, environmental protection, medical and health care, etc., and can also directly provide power for micro-machin...
