Abstract
Powder charge operated setting tool includes a barrel (11) and a closing or breech member (17), axially displaceable within a housing 1. Stops (3a, 17a) and shoulders (8b, 11e) cooperating with each other are provided in the housing (1) and on the barrel (11) as well as on the closing member (17) which limit displacement of the barrel (11) and, after an additional displacement travel, the displacement of the closing member (17) counter to the setting direction. As a result a free space is formed between the barrel (11) and the closing member (17) which permits feeding of propellant charges (15), especially in magazines, perpendicularly to the axis of the barrel.
