DEVICE FOR CONTROLLED OPERATION OF A SURGICAL OR DENTAL DRIVE UNIT

摘要

A device for operation of a surgical or dental drive unit comprises 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. This control valve includes a first control arrangement, a control switch and a control sleeve. The first control arrangement controls a rate of flow of the compressed fluid through the control valve. The control sleeve is 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.
