PRESSURE FLUCTUATION ABSORBING DEVICE

Japanese Patent JP3651811

B

PURPOSE: To provide a pressure fluctuation absorbing device which can effectively absorb pressure fluctuation with pressure loss restrained low by a simple structure.
CONSTITUTION: This pressure fluctuation absorbing device has a partition 24 for partitioning a main body 21 into air-chambers 22, 23; an introduction port 25; a discharge port 26; a cylindrical body 27 which is fixed to the upper face of the partition 24 at its lower end; and a float 28 arranged inside the cylindrical body 27. A gas introducing opening 29 is provided on the bottom of the cylindrical body 27, and the upper side of the cylindrical body 27 is closed by an upper wall 30. A sliding member 42 slides in a throttle opening 31 functioning as a variable throttle on the side wall of the cylindrical body 27 to prevent the clogging of the throttle opening 31. The small hole 32 of the upper wall 30 makes the air-chamber 33 function as a cushioning mechanism for controlling the abrupt movement of the float 28 to prevent hunting. The sliding member 41 slides in the small hole 32 with the vertical movement of the float 28 to prevent the clogging of the small hole 32.
