Patent number: 4476942Abstract: An inlet control valve particularly useful in connection with pneumatic tools or the like. The valve includes a longitudinally depressible member passing loosely through a frusto-conical plug in a matching frusto-conical valve seat. In the closed position, the plug is seated and the stem is sealed by an O-ring. As the trigger is depressed, the O-ring first releases a path for fluid flow about the shaft within the plug providing an idle speed. Further depressing of the trigger causes a shoulder to contact the plug and, thereafter, move the plug rearward which provides an increasing amount of fluid flow around the plug proportional to the amount of depression thus providing a variable speed.Type: GrantFiled: April 28, 1982Date of Patent: October 16, 1984Assignee: Monogram Industries, Inc.Inventor: Robert D.
