Sprüh-Beschichtungspistole für Baustoff

摘要

The gun has a cylinder pneumatically actuatable under the control of a user to oppose itself to a return force exerted by a return unit (26) to respectively induce the release or closure of an opening. The cylinder has a piston (22) associated to a rod (18) whose free end (20) cooperates with an upstream end of a nozzle (14) in a relatively tight manner to close the nozzle.
