   PATENT-ANSPRÜCHE :
1. Luftpumpe, insbesondere für Automobilreifen, mit mehreren ineinander verschiebbaren, mit Kupplungen ausgerüsteten Kolben, dadurch gekennzeichnet, dass auf der als Zylinder für den Hochdruckkolben (4) ausgebildeten hohlen Kolbenstange   (3)   des Niederdruckkolbens (2) eine Klinke (6) gelagert ist, die durch einen Sperrhaken (7) in eine Ringnut   (9)   des Hochdruckkolbens   (4)   eingreift und diesen mit der Kolbenstange (3) des Niederdruckkolbens (2) kuppelt, solange ihr Ansatz (13) auf einem Gleitstück   (12) aufruht,   das durch einen   Bi\gel (11)   mit einer an der Klinke befestigten Feder   (10)   verbunden ist, und erst dann freigegeben wird, wenn nach beendigtem Verdichtungshub des Niederdruckkolbens (2) ein Ansatz (15)

   des Zylindersdeckels (14) das Gleitstück   (12)   zurückgeschoben und dadurch das Eindringen des Kinkenansatzes (13) in die   Nut (16)   am Zylinderdeckel   (14)   gestattet hat, wodurch der Zylinder (1) für die Dauer der   Rückwärtsbewegung   des Hochdruckkolbens (4) mit der Stange (3) des Niederdruckkolbens   (2)   gekuppelt ist.

 between which there is one of the longitudinally extending web 20, which is formed by the remaining part of the pipe jacket u'd. At the end of the rod 18 of the piston 4 is provided with cutouts 21 which allow the web 20 to be slipped on. From the bottom
 EMI2.1
 Rotation of the handle arrives, so that the slots with the web form a kind of rotary slot lock.



   PATENT CLAIMS:
1. Air pump, in particular for automobile tires, with several reciprocally displaceable pistons equipped with clutches, characterized in that a pawl (6) is mounted on the hollow piston rod (3) of the low-pressure piston (2) designed as a cylinder for the high-pressure piston (4) , which engages through a locking hook (7) in an annular groove (9) of the high-pressure piston (4) and couples it to the piston rod (3) of the low-pressure piston (2) as long as its extension (13) rests on a slider (12) that is connected by a bracket (11) to a spring (10) attached to the pawl, and is only released when, after the compression stroke of the low-pressure piston (2), a shoulder (15)

   of the cylinder cover (14) has pushed the slide (12) back and thereby allowed the penetration of the pawl attachment (13) into the groove (16) on the cylinder cover (14), whereby the cylinder (1) for the duration of the backward movement of the high-pressure piston (4) is coupled to the rod (3) of the low-pressure piston (2).

Claims (1)

2. Luftpumpe nach Anspruch 1. dadurch gekennzeichnet, dass ihr Handgriff aus einem in den hohlen Pumpenkolben einsteckbaren Rohrstück besteht, das mit Ausschnitten versehen ist und mit entsprechenden Ausschnitten des Endes der Kolbenstange einen Drehscblitzverschluss bildet. 2. Air pump according to claim 1, characterized in that its handle consists of a tubular piece which can be inserted into the hollow pump piston and which is provided with cutouts and forms a rotary flash shutter with corresponding cutouts at the end of the piston rod.
