A pump including a stator, a rotor comprising an axial extension slidably and rotatably mounted at least partially in a rotor chamber of the stator, and at least first and second valves between an inlet and the rotor chamber, respectively between the rotor chamber and an outlet, that open and close as, a function of at least the angular displacement of the rotor. The pump comprises interacting cam elements on the rotor and stator and biasing elements acting on the rotor for applying a force on the rotor in the axial direction of the stator cam elements.

Micropump

A pump system having a pump module () comprising a stator housing () with a chamber (), a rotor () rotatably and axially slidably received in the chamber and comprising a first axial extension () with a liquid supply channel () and a second axial extension with a liquid supply channel (), the first and second axial extensions having different diameters, and first and second sealing rings (), mounted around the first and second axial extensions.

Pump system

An arrangement for the control of an operating installation of a building automation system is disclosed. The arrangement comprises a control module serving as a master transmitter-receiver and at least one function module serving as a slave transmitter receiver. A bus connection including a bus rail connects the control module and the at least one function module for the transmission of addresses and data and for the transmission of operating voltages. The bus rail is installed electrically at the periphery of the installation so that the at least one function module is connected to a plurality of conductors forming the bus rail and directly to the installation so that the function module serves as an input/output terminal of said installation for the transmission of process parameters.
