Abstract

Es werden vorsteuerbare Wegeventile (10, 58, 60) vorgeschlagen, die durch ihre Bauweise die Ausbildung von ebenfalls vorsteuerbaren Ventileinheiten (50) erlauben, welche als sitzgesteuerte Impulsventile oder als Umschaltventile in außendichtender bzw. innendichtender Bauform ausführbar sind.Pre-controllable directional valves (10, 58, 60) proposed the training of allow valve units (50) which can also be piloted, which as seat-controlled pulse valves or as Changeover valves in external or internal seals Design are executable.

Die Wegeventile (10, 58, 60) weisen dazu Sitzkörper (18, 20, 68, 70) mit unterschiedlich großen Ventilöffnungen auf. Ferner sind die Ventilschieber (26, 64) mit Steuerkolben (32, 34, 82, 84) unterschiedlich großer Kolbenflächen ausgestattet, die jeweils in separaten Steuerkammern (38, 40, 96, 100) geführt sind.

Figure 00000001
The directional control valves (10, 58, 60) have seat bodies (18, 20, 68, 70) with valve openings of different sizes. The valve spools (26, 64) are also equipped with control pistons (32, 34, 82, 84) of differently sized piston surfaces, each of which is guided in separate control chambers (38, 40, 96, 100).
