Pump for supplying liquids

Abstract: The pump (1) has a housing (4) including a drive region (2) and a pumping region (3). A drive shaft (5) and a running wheel (6) are located on the drive shaft. 0.1-1.5 mm axial gap dimension (S1) is provided between the housing and a cover disk of the running wheel. The drive shaft is mounted in the drive region and in the pumping region with bearings (7, 7', 7''). An axial spacing (A) between the running wheel and one of the bearings of the drive shaft is smaller or equal to diameter (D) of the running wheel.

Device for ventilating a vehicle seat and vehicle seat

Abstract: The invention relates to a device for ventilating a vehicle seat, said device comprising: a cushion (12) which is elastic with respect to a user contact and which is designed to form a seating surface and/or a contact surface (24) for the back, said cushion having an air flow channel (16, 17) which forms an air outlet (15) in the direction of the seating surface and/or contact surface for the back; a cover unit (18) designed to at least partially cover the air outlet, the unit being air-permeable, rigid and preferably having a lattice-type construction; and a fan unit (14) which is associated with the air flow channel and which has an electric motor-driven fan rotor (30) and a fan housing (32), some sections of which housing radially surround the fan rotor. The cover unit and the fan unit are mutually spaced (d) along the air flow channel and preferably are secured to or in the cushion without a direct connection to sections of said cover unit and fan unit. Preferably, a mechanical connection between the cover unit and the fan unit is achieved only by a flexible, rubber-elastic material, especially preferably a foam-type material of the cushion (12).

Netzwerkkonfiguration und Verfahren zur Vergabe von Netzwerkadressen an Ventilatoren in einem Netzwerk

Abstract: Die vorliegende Erfindung betrifft ein Verfahren zur Konfiguration eines Netzwerks (10) mit Netzwerkadressen (ID), wobei das Netzwerk (10) aus wenigstens einem Zentralrechner (20) und eine Vielzahl an Ventilatoren (30) besteht, welche uber ein Bus-System (11) drahtgebunden und/oder drahtlos mit dem Zentralrechner (20) kommunizieren konnen, wobei jeder Ventilator (30) uber einen wiederbeschreibbaren Speicher (31) und eine RFID-Schnittstelle (32) zur Kommunikation mit einem vorzugsweise mobilen Kommunikationsgerat (33) verfugt, wobei im Speicher (31) des jeweiligen Ventilators dessen Seriennummer (S) abgespeichert ist und die Seriennummer (S) im nicht betriebsbereiten spannungsfreien Zustand des jeweiligen Ventilators (30) von dem Kommunikationsgerat (33) ausgelesen werden kann

Wall ring with wall ring heating element for axial fans

Abstract: The invention relates to a wall ring for receiving an axial fan (6) in particular, comprising an annular body (1) with a central longitudinal axis (X-X), a flow inlet opening (2), a flow outlet opening (3), and an electric heating element in particular, said heating element being arranged on at least some sections of the circumference of the annular body (1). A profiled covering section (9) made of a thermally insulating material is removably fixed to an outer surface of the annular body (1) at least in some sections of the circumference, said profiled covering section together with the annular body (1) forming a receiving area in the region of the annular wall (4) of the annular body in order to receive the electric heating element.

Rotational body, particularly rotor of electric motor, is rotatable around assigned rotational axis and has annular path that is concentrically arranged to rotational axis

Abstract: The rotational body (100) is rotatable around an assigned rotational axis (150) and has an annular path that is concentrically arranged to the rotational axis. Two measuring bodies are arranged in the assigned balancing positions in the path. A light-setting viscous fixing material is sectionally provided in the path and fixes the measuring bodies in the assigned balancing positions. The curable viscous fixing material is an adhesive and particularly a light-setting cyanoacrylate- or acrylate adhesive. An independent claim is also included for a method for balancing a rotational body.
