Abstract
A device for operation of a surgical or dental drive unit includes a control valve attached to a drive unit to control a flow rate of a compressed fluid flowing from a compressed fluid source to the drive unit. The control valve includes (a) a first control arrangement controlling a rate of flow of the compressed fluid through the control valve; (b) a control switch; and (c) a control sleeve controlled by the control switch to axially move along a longitudinal axis of the drive unit between a first configuration in which the control valve is locked and closed to fluid flow and a second configuration in which the control valve is unlocked and the first control arrangement controls the rate of flow therethrough.
