Fuel gas pressure governor installation structure null of thermal

摘要

PURPOSE:To suppress variation of setting of pressure regulator and to lengthen the service life of inner parts by communicating the atmospheric pressure chamber formed in the pressure regulator of gas engine through a tubular path to the outside of engine containing box. CONSTITUTION:The atmospheric chambers 26, 29 formed in the pressure regulator 7 of gas engine are communicated through tubular paths 45-48 to the outside of engine containing box 3. Consequently, variation of ambient pressure in the atmospheric pressure chamber is suppressed to reduce variation of setting of pressure regulator. While the temperature in the atmospheric chamber is maintained low to prevent deterioration of rubber product.
