Abstract

A linear valve drive for connection to a valve body which has a valve seat is described, wherein said linear valve drive comprises a drive housing, a valve closure element and a piezoelectric actuator which is arranged within said drive housing. Said valve closure element is displaceable in the axial direction between an open position and a closed position by means of said piezoelectric actuator and an interposed actuating device. Said piezoelectric actuator is supported on said actuating device via its side directed towards the valve closure element. Said linear valve drive comprises an adjusting device which is configured such that an idle stroke of said linear valve drive is adjustable. A valve is also described.
