<p>PROBLEM TO BE SOLVED: To enable forcible valve-opening of a valve mechanism for a predetermined time at all times before engine start to properly fill a secondary fuel passage with gas fuel.SOLUTION: A fuel regulating valve of a gas engine is interposed between a primary fuel passage 11 and a secondary fuel passage 12 and comprises: a valve mechanism 21 which is connected to a diaphragm 16 dividing the inside of a case 15 into a pressure regulation chamber 17 and a fuel chamber 18 connected to the secondary fuel passage 12, can open and close between the primary fuel passage 11 and the fuel chamber 18, and is spring-biased in the close direction; and a forcible valve-opening mechanism 21 having an operation member 44 which is movable between a non-operation position N and an operation position Y and is biased to a non-operation position N side by a return spring 47. The operation member 44 is connected to a valve-opening means 54 which opens the valve mechanism 21 when the operation member moves from the operation position Y to the non-operation position N, and to a damper 58 slowing return motion from the operation position Y to the non-operation position N, which is caused by the return spring 47.</p> |
