 einer durch den Deckel hindurchgeführten Kurbelwelle g von aussen bedient werden kann und dabei die der   Staubablagerullg ausgesetzten   Flächen bestreicht. Im vorliegenden Falle ist, der Gestaltung des Deckels und Kolbens entsprechend, die Bürste als flache Scheibe ausgebildet und die Welle durch die Mitte des Zylinderdeckels   hindurchgeführt,   so dass nach Aufsetzen einer Handkurbel auf das vierkantige Ende d der Welle die Bürste um die Zylindermitte gedreht werden kann und hiebei die   gesamte Innenfläche   bestreicht. Da auch auf der entgegengesetzten Seite 
 EMI1.5 
 Feder e   hineingedrückt     wird.

   Bei Inbetriebsetzung drückt man   die Welle gegen die Federkraft nach   Innen,   so dass die Bürste aus ihrer Aussparung heraustritt. Es   genügen   wenige Umdrehungen, um die gesamte Ablagerung zu beseitigen. Die Staubteile fallen alsdann in den Ventilraum   1.   und werden bei der nächsten Inbetriebsetzung der Pumpe abgezogen. Zur Unterbringung der Welle g und der Feder e ist zweckmässig an dem Deckel eine besondere Büchse anzuordnen, die während des   Punpenbetriebes   durch eine Kapselmutter f luftdicht geschlossen gehalten wird. 



  An Stelle der Bürste   kann natürlich   auch ein ähnlich   wirkendes schabendes Werkzeug in gleichem   Sinne benutzt werden.

 a crankshaft g passed through the cover can be operated from the outside and in doing so it sweeps the surfaces exposed to the dust deposit. In the present case, according to the design of the cover and piston, the brush is designed as a flat disc and the shaft is passed through the center of the cylinder cover so that after placing a hand crank on the square end d of the shaft, the brush can be rotated around the center of the cylinder and brushed the entire inner surface. Since also on the opposite side
 EMI1.5
 Spring e is pressed in.

   When starting up, the shaft is pushed inwards against the spring force so that the brush emerges from its recess. A few turns are sufficient to remove the entire deposit. The dust particles then fall into valve chamber 1. and are removed when the pump is next started up. To accommodate the shaft g and the spring e, a special sleeve is expediently to be arranged on the cover, which is kept airtightly closed by a cap nut f during the pump operation.



  Instead of the brush, a similarly acting scraping tool can of course also be used in the same sense.

Claims

EMI2.1 The shaft guided by the cylinder cover is provided and rotated by a hand crank placed on it.

3. Apparatus according to claim 1 and 2, characterized in that the brush sweeps the entire inner surface of the cylinder cover together with the abutting corners as well as the face of the piston as soon as it is brought close to it.

4. Apparatus according to claim 1 to 3, characterized in that the brush is designed as a thing, all sides occupied with bristles disc.

5. Apparatus according to claim 1 to 4, characterized in that the brush lies in a groove-shaped recess of the cover when not in use.

6. Apparatus according to claim l to 5, characterized in that the crankshaft guided through the cylinder center of the brush when not in use under the action of a spring is pushed outwards and into the recess, while in use it is pushed out of this position by means of the edge crank.

7. Apparatus according to claim l to 6, characterized in that the crankshaft together with the spring is arranged in a sleeve placed on the cover which is kept airtightly closed by a capsule nut during operation of the pump.
