摘要： PROBLEM TO BE SOLVED: To provide a gas engine fuel supply device with a vaporizer for efficiently promoting the vaporization of liquefied fuel while removing nonvolatile components. SOLUTION: The gas engine fuel supply device comprises the vaporizer 15 for gasifying liquefied fuel fed from a fuel cylinder 16, a regulator 10 for regulating the pressure of the gasified fuel fed from the vaporizer 15, and a mixer 3 for mixing the gasified fuel fed from the regulator 10 with air to be supplied to a gas engine E. The vaporizer 15 has a vaporization promoting member 24 formed of a filter material with a number of continuous pores. COPYRIGHT: (C)2007,JPO&INPIT

摘要： PROBLEM TO BE SOLVED: To provide sufficient valve opening force on an open and close valve opening and closing a fuel passage of a regulator for a gas engine and prevent enlargement of the regulator. SOLUTION: The open and close valve 15 is provided between the fuel passages 1a, 1a making gas fuel flow to an intake pipe 3. A rod 25 provided to face the open and close valve 25 is supported by a support hole 21a of a vacuum cock main body 21 slidably in a linear motion direction. A small diameter diaphragm 2 is connected on one end of an open and close valve side of the rod and a large diameter diaphragm 26 is connected to another end. A vacuum chamber 23 is formed between both of the diaphragms, and displace the rod in the open and close valve side by difference of pressure receiving areas to open the open and close valve when intake vacuum acts thereon. Since force other than linear displacement direction of the rod does not act on the diaphragms, displacement of the diaphragm is stabilized and durability thereof is improved. Valve open action is also stabilized by linear motion. COPYRIGHT: (C)2007,JPO&INPIT
摘要翻译：要解决的问题：为了在打开和关闭阀打开和关闭用于燃气发动机的调节器的燃料通道上提供足够的阀打开力，并且防止调节器的扩大。解决方案：打开和关闭阀15设置在使气体燃料流入进气管3的燃料通道1a，1a之间。设置成面向打开和关闭阀25的杆25由支撑孔21a支撑真空旋塞主体21沿直线运动方向滑动。小直径隔膜2连接在杆的打开和关闭阀侧的一端，大直径隔膜26连接到另一端。在两个隔膜之间形成真空室23，并且通过压力接收区域的差异使开启和关闭阀侧的杆移动，以在进气真空作用在其上时打开和关闭阀。由于杆的线性位移方向以外的力不对膜片作用，所以隔膜的位移被稳定，其耐久性提高。阀门打开动作也通过线性运动来稳定。版权所有（C）2007，JPO＆INPIT

摘要： PROBLEM TO BE SOLVED: To implement a simple structure which enables the switching of a heterogeneous gas fuel as well as the setting of other components.
SOLUTION: A heterogeneous gas fuel switching pressure regulator is provided with a propane port 3a to communicate with a propane gas cylinder, a butane port 9a to communicate with a butane gas cylinder, and fuel flow-out passage 4a to communicate with a throttle valve 17. Valve bodies 18a to 18d which open and close in comformity with the rotation position of the switching member 11 between both the flow-in passage and fuel flow-in passage are arranged in the flow-in side and flow-out side by two. Each valve body becomes in two states where only butane or only propane is passed and three states where both are totally enclosed. Respective jets 16a and 16b are provided on the downstream side of each valve body at the fuel flow-out passage to make a suitable fuel feed pressure corresponding to each gas fuel. Switching operation of the switching member enables the selection to feed the selected gas fuel into an engine under the corresponding fuel feed pressure. The heterogeneous gas fuel switching pressure regulator can be implemented to enable the proper use of several kinds of gas fuel with this simple construction.
