ABSTRACT:
A nozzle head of thermoplastic material injection nozzle is closed in the customary manner with a closure head which has a jet orifice. A jet needle closes the jet orifice in a closed position. The needle is held axially displaceable in a needle bearing. An actuation lever is set into a slit-like recess in the needle bearing and it is supported with a bearing ball carried at the rear wall of the needle bearing. A stroke transmission bolt set inbetween jet needle and actuation lever in overhung position serves for transmitting the closing force from the actuation lever to the jet needle. Upon opening, the injection pressure pushes the jet needle rearward if the actuation lever is rotated into the open position. In this arrangement a locking spring becomes superfluous and, consequently, no force counter to the spring force must be effected by the injection force.
