1. An electrofluidic assembly, comprising:
- at least one electrofluidic pump assembly;
an electrofluidic valve;
wherein both the pump assembly and the valve are activated by in each case one electromagnet;
wherein the pump assembly and the valve are arranged on an identical central line and use a bearing rod jointly for movable bearing of a first solenoid armature which activates a displacement apparatus of the pump assembly on one hand and a second solenoid armature of the valve which activates a group of closing bodies on the other hand.

Abstract
An electrofluidic assembly and method for its operation. The functions of a reciprocating pump and of a valve should be combined in one assembly. Here, in particular the pump and the valve should interact so that a small number of line connections are required. A pump assembly and a valve are arranged on an identical central line and use a bearing rod jointly for movable bearing of a first solenoid armature which activates a displacement apparatus of the pump assembly on one hand and a second solenoid armature of the valve which activates a group of closing bodies on the other hand. The electrofluidic assembly can be used for monitoring tank systems.

11. A method for operating an electrofluidic assembly, which contains at least one electrofluidic pump assembly and an electrofluidic valve, wherein both the pump assembly and the valve are activated by an electromagnet or by in each case one electromagnet, the method comprising:
-
an electric control unit connected to the electrofluidic assembly actuates the electromagnets in such a manner that, a fluidic pressure difference is built up at an outlet in that, in the case of a closed valve, the electromagnet of the pump assembly is energized in a clocked manner, wherein a solenoid armature correspondingly moves a displacement apparatus and wherein fluid is conveyed and in this case a gas pressure in a connected tank is increased or reduced; the clocked energization of the electromagnet of the pump assembly is terminated and the valve is held closed by an energization of its electromagnet; a pressure profile in a connected tank is measured in that a pressure sensor connected to the outlet or to a supply line to the tank transmits the profile of the pressure in the tank to the electric control unit, wherein the profile of the pressure is recorded in the electric control unit; after a defined time Tv, measurement and recording of a second pressure profile are carried out; the two pressure profiles are compared with one another and the imperviousness of the tank is concluded from the difference between the two pressure profiles; and the pressure in the tank is reduced, the valve is opened in that the associated electromagnet is deenergized. - View Dependent Claims (12, 13, 14)
