Abstract

The invention provides a fuel supply device used in a gas engine, which has an integral structure and functions of automatic switching, two-way controlling, balancing and mixing, can enable the gas engine to work normally within a pressure range of between100 and minus 10kPa, and is particularly applicable to the low pressure gas source fields, such as oilfield associated gas, methane, gas and soon.

Description

Background technique [0001] Existing gas engine new fuel supply device: one valve multi-door large flow single-stage decompression regulator (patent application number 200710088040.6), used for air and gas input pressure balancer of gas engine mixer (patent application number 200710301002.4), with Vacuum constant pressure and mixer (patent application number 2005100546327) for gas engines; these new devices have their own unique features, but the overall combined structure is not compact, inconvenient to use, and the cost is relatively high. Contents of the invention [0002] The purpose of the present invention is to: optimize the overall structure of the prior art, reduce manufacturing cost and improve practicability. [0003] The present invention achieves its purpose in the following manner: it is composed of a two-way decompression mixer body, a gas pressure relief valve, an air pressure relief valve, a constant pressure mixing valve, and a diaphragm; port, mixed gas o...
