Abstract
An actuating drive for a pneumatic valve of an insertion head for electrical components having a revolver type movable insertion head for the electrical components which includes suction pipettes which protrude in a stellate fashion and which can be rotated successively into a placement attitude for each respective component. A valve is allocated to each of the suction pipettes which switches its suction air over to blowing air following placement of the component on a components carrier. The valve is actuated by a piezoelectric flex transducer anchored at a stator of the insertion head.
