摘要： PROBLEM TO BE SOLVED: To provide a pressure reducing valve for supplying stable reduced pressure and gas flow by suppressing secondary pressure from overshooting or chattering, which could occur when the valve element of the pressure reducing valve opens or closes a connection.
SOLUTION: The pressure reducing valve 1 includes an inlet 21 for a primary fluid; an outlet 31 for a secondary fluid; a valve chamber 2 provided with a valve seat 29 at a connection 28 to the inlet 21; a valve element 40 having a sealing member 48 for pressing the valve seat 29 and movably disposed within the valve chamber 2 to press the seal member 48 against the valve seat 29 by means of the pressure of the secondary fluid; and an energizing member for energizing the sealing member 48 in the direction away from the valve seat 29. When the pressure of the secondary fluid reaches a predetermined pressure, the connection is closed. When the pressure of the secondary fluid drops below the predetermined pressure, the connection 28 is opened. The pressure reducing valve has a buffer means for reducing the moving speed of the sealing member 48 when the sealing member 48 opens or closes the valve seat 29.

摘要： PROBLEM TO BE SOLVED: To provide a check valve of simple structure capable of preventing increase of the size thereof.
SOLUTION: The check valve 1 is provided with a flow-in opening 33, a flow-out opening 34, a housing part 4 formed with a valve element housing space 11 and a valve element 7 housed in the valve element housing space 11. The valve element 7 has a valve element main body 5 and a seal member 6 separated into a plurality of projecting pieces 29 and 30 in a downstream side end thereof, and when fluid flows into from the flow-in opening 33, an interval between the plurality of projecting pieces 29 and 30 is reduced by the fluid pressure, and the fluid passes through a clearance between the seal member 6 and the inner wall 25 of the housing part 4, and flows out from the flow-out opening 34. When the fluid reversely flows from the flow-out opening 34, the interval between the plurality of projecting pieces 29 and 30 is increased by the fluid pressure, and the most outside projecting piece 30 abuts on the inner wall 25 of the housing part 4 to shut off a flow of the fluid.
