Pump cylinder and method of collecting pasty materials, liquids, gases and/or mobile objects
First Claim
1. A pump cylinder comprising:
- a) a pump plunger guided in and dividing the cylinder into a forward and a rearward subspace;
b) the forward subspace has a connection for taking in a fluid medium to be delivered;
c) the rearward subspace contains at least one electrochemical cell for a consumption gas;
d) an electric circuit being constantly or temporarily connected with electrodes of the cell;
e) the rearward part of the pump cylinder being filled with an electrochemical consumption gas and being closed;
f) the cell being a gas consumption cell for the consumption gas; and
g) the electric circuit having a working resistor and is designed for causing a gas consumption current so that the pump cylinder forms a device for collecting pasty masses, liquids, gases and mobile objects for a predetermined time period.

Abstract
A pump cylinder in which a pump plunger is guided which divides the cylinder into a forward and a rearward subspace, which, in the forward subspace, has a connection for taking in the fluid medium to be delivered, the rearward subspace of the pump cylinder containing one or several electrochemical gas consumption cells for a consumption gas, an electric circuit being provided which is constantly or temporarily connected with the electrodes of the gas consumption cell, is characterized in that the rearward part of the pump cylinder is filled with an electrochemical consumption gas, and the electric circuit is designed for causing a gas consumption current so that the pump cylinder forms a device for implementing a process for collecting pasty masses, liquids, gases and mobile objects for a previously determinable time period.
