  • Pneumatic pressure relief assembly
    Patent number: 5331999
    Abstract: Apparatus and method are disclosed by which a pent up supply of compressed air in a pneumatic supply line is slowly bled off after the line is disconnected from its air supply source. The apparatus and method are well adapted for use in pneumatic tool lines. The invention includes a housing which may be inserted in a line attached to a supply of high pressure air, such as a pneumatic line. Flow restriction means are contained in a passageway within the housing for permitting the relatively free flow of pressurized air in one direction, such as is needed to operate a pneumatic tool, and for partially restricting the flow of air in the opposite direction once the line has been disconnected from its supply source.
