摘要:
An arrangement in combination with an oscillating cylinder (1), whereby the arrangement includes a working valve (10) of cylinder (1) to transmit pressure medium into cylinder (1), impulse valves (5) by means of which, by working valve is controlled, control means (4), as discs, from movable piston rod (18) to cylinder (1) outside, which can be arranged to get in several different linear positions in contact with the control means impulse valves (5) in order to produce a stroke length set for the piston rod of the oscillation cylinder. In the arrangement the impulse valves are placed sideways outside control means (4) and the required impact to be achieved from the control means (to the impulse valves (5) is moved by means of special arms (13) moved from control means (4) as an opening/closing motion of the shut-off part of the impulse valves whereby the structural length of the oscillating cylinder can be achieved essentially shorter in the cylinder back end of control means (4), (5).
摘要:
The invention relates to a rotary actuator, converting actuator and method for producing rotation. The rotary actuator includes at least two rotation units for producing stepped angular displacements (Rs). The rotation unit includes a cylinder for producing linear movement (L) and a converter for converting the linear movement to rotation. The stepped rotary movements of the rotation units are transmitted by transmission elements to an output shaft.
摘要:
Es wird eine pneumatische Oszillatorvorrichtung (1) vorgeschlagen, bei der in einer Oszillationskammer (3) eines Oszillatorgehäuses (2) ein Oszillatorkolben (13) linear hin und her verschiebbar angeordnet ist. Umfangsseitig in die Oszillationskammer (3) münden ständig an eine Druckluftquelle angeschlossene Zuluftöffnungen (22a, 22b) und ständig an eine Drucksenke angeschlossene Ablüftöffnungen (18a, 18b). Bezüglich diesen Öffnungen fungiert der Oszillatorkolben (13) als Ventilglied, indem er sie positionsabhängig so mit stirnseitigen Arbeitskammern (14a, 14b) verschaltet, dass in den beiden Endlagen einander entgegengesetzte Druckdifferenzen zwischen den Arbeitskammern (14a, 14b) vorliegen.
