Abstract
Die Steuerung ist dabei derart ausgebildet, daß der Steuerschieber (15) - in Abhängigkeit von der Stellung des Schlagkobens (3) - eine Arbeitshub- bzw. eine Rückhubstellung einnimmt.
In der Arbeitshubstellung ist der Schlagkolben (3) derart mit dem Arbeitsdruck beaufschlagt, daß er - entgegen der Wirkung einer ständigen Rückstellkraft - einen Arbeitshub (Pfeil 6) ausführt; im Gegensatz dazu ist der Schlagkolben (3) in der Rückhubstellung derart an eine Ablaufleitung (17) angeschlossen, daß er unter Einwirkung der Rückstellkraft einen Rückhub ausführt.
Die Laufbuchse (2) - deren dem Außengehäuse (4) zugewandte Außenfläche (2g) gemeinsam mit diesem zumindest einen in Längsrichtung dieser beiden Teile verlaufenden, für den Schlagkolben-Rückhub benutzten Druckmittelkanal (12) bildet - ist zumindest über eine derartige Längserstreckung einteilig ausgebildet, daß der dem Werkzeug zugewandte vordere Führungsabschnitt (2b) und zumindest sich etwa an diesen in Rückhubrichtung anschließende weitere Führungsabschnitte bis zum Führungsabschnitt (2a) für die größere Kolbenfläche (A1) einschließlich Bestandteil der Laufbuchse sind.
