始動減圧装置。 A cylindrical chamber 4 is formed in a main body 3 attached to a cylinder 2 of an internal combustion engine, and a piston valve 5 is disposed in the cylindrical chamber so as to be able to reciprocate. The shaped chamber is partitioned into a front chamber 7 and a rear chamber 8, a communication passage 9 communicating between the front chamber and the rear chamber is formed in the large diameter piston portion, and the front chamber is communicated with the combustion chamber 14 of the cylinder. At the same time, a front valve part 16 is formed in the piston valve to block communication of the front chamber to the combustion chamber, and to communicate the rear chamber to the outside, while blocking communication of the rear chamber with the outside in the piston valve. forming a rear valve portion 18 that
Further, a spring 17 is provided which acts on the piston valve so as to maintain the front valve part in the closed position with a predetermined pressing force and to maintain the rear valve part in the open position when the internal combustion engine is stopped. Starting pressure reducing device for internal combustion engines.
