Abstract

Für das Aufblasen und Entleeren eines Luftpolsters, insbesondere für Schischuhe, wird eine Pumpe (1) mit einer Ventilanordnung vorgeschlagen, welche zwei Ventile (3 und 4) umfaßt. Die beiden Ventile (3 und 4) sind so angeordnet, daß nach Betätigung des Betätigungsgliedes (9) des Einla­ ßventiles (3) und nach einem vorbestimmten Hub dieses Ventil mit dem Betätigungsglied (12) eines zweiten Ventiles (4) zusammenwirkt. Das zweite Ventil (4) ist ebenso wie das erste Ventil (3) als Rückschlagventil ausgebildet. Aus dem Pumpenraum der Pumpe (1) kann somit unter Aufdrücken des Rückschlagventiles (4) bei gleichzeitigem Geschlossen­ halten des Ventiles (3) Luft aus dem Pumpenraum in einen Luftpolster (8) gepreßt werden. Zum Ansaugen weiterer Luft in die Luftpumpe (1) schließt das Rückschlagventil (4) selbsttätig, wobei für das Ansaugen das Ventil (3) geöffnet wird. Schließlich wird für das Entleeren von Luft aus dem Polster (8) und der Vermittlung des Ventiles (3) das Ventil (4) aufgestoßen, so daß die Luft über beide Ventile entweichen kann. For inflating and deflating an air cushion, especially for ski boots, a pump (1) with a Valve arrangement proposed, which two valves (3 and 4) includes. The two valves (3 and 4) are arranged that after actuation of the actuator (9) of the inlet ßventiles (3) and after a predetermined stroke this Valve with the actuator (12) of a second valve (4) interacts. The second valve (4) is just like that first valve (3) designed as a check valve. From the Pump chamber of the pump (1) can thus be pressed on the check valve (4) with simultaneous closing hold the valve (3) air from the pump room into one Air cushion (8) are pressed. For sucking in more air the check valve (4) closes in the air pump (1) automatically, whereby the valve (3) is opened for suction becomes. Finally, for the evacuation of air from the Upholstery (8) and the mediation of the valve (3) the valve (4) pushed open so that the air escapes through both valves can.
