Abstract

Die Erfindung ist eine Kombinationsschraube (1) zur Befestigung eines Ventilblocks (5) an einer Hydraulikkolbenmaschine (6) und zur Fixierung und/oder Verstellung einer Steuereinrichtung, wobei die Kombinationsschraube (1) als ein Bauteil ausgebildet ist und wobei die Kombinationsschraube (1) zumindest in einem Teilbereich als Hohlschraube ausgebildet ist und wobei der Hohlraum als Strömungskanal (7) für Hydraulikflüssigkeit dient und wobei die Kombinationsschraube (1) mindestens folgende Merkmale aufweist: eine obere Hydraulikflüssigkeitsaustrittsöffnung (9) aus dem Strömungskanal, eine Drehmomentaufnahmeeinrichtung (3) zur Aufnahme eines Drehmoments zum Fixieren und/oder Lösen der Kombinationsschraube (1), insbesondere eine Schlüsselfläche, vorzugsweise eine Sechskantschlüsselfläche, mindestens eine Anlagefläche (10), vorzugsweise unterhalb der Drehmomentaufnahmeeinrichtung (3), mindestens eine, insbesondere vier, seitliche Auslasskanäle (11) aus dem Strömungskanal in der Schraubenwand, mindestens ein, vorzugsweise unterhalb des seitlichen Auslasskanals gelegenes, Außengewinde (18), eine oder mehrere untere Hydraulikflüssigkeitseinlassöffnungen (8) in den Strömungskanal (7), einen unteren Fixier- und/oder Verstellfortsatz (16). Die Erfindung vereinfacht die Befestigung eines Ventilblocks (5) an einer Hydraulikkolbenmaschine (6) mit verdrehbarer Steuerscheibe.
