摘要： Cartridge sealing comprising an outer ring and an inner ring (1, 2) of opposite angular profile which together enclose an annular space (3) having a concentrically conceived axis (9), the outer ring (1) being provided with at least one sealing lip (4), which rests against the inner ring (2), the annular space (3) and the space sealed off communicating via a gap (5) bounded on one side by a flange (6) connected to the inner ring (2), the cross-section of the gap (5) being widened on the side facing away from the flange (6) in segmental cut-outs (7), distributed over the circumference of the outer ring (1), which form channels that connect the annular space (3) and the space to be sealed off, the channels being bounded in the axial direction, on the side facing the flange (6), by a conically sloping run-off surface (8) which forms part of a diameter concentrically surrounding the axis (9) and widened in a funnel shape in the direction of the annular space (3). In the axial direction, the run-off surface (8) surrounds the flange (6) completely and the sealing lip (4) at least partially. … …

摘要： Water/air heating boiler with a double casing, open at the front and with water flowing through it, having water-conducting transverse pipes, a further casing arranged at a spacing at least from one side wall and/or the rear wall of the double casing, and enclosing between it and the double casing an interspace conducting an air stream, at least one essentially horizontally arranged air heating duct going out from the interspace and traversing the fire space, and the air heating duct and the water-conducting transverse pipes take up separate partial regions of the fire chamber head, a fire basket (31) being movably arranged beneath the fire chamber head. The heating boiler furthermore has an air-permeable base (18) with an ember box (23) arranged approximately centrally in the base and having the air flowing towards the interspace (17) flowing around it. In the embodiment as a variable fuel boiler, the base (18) can be divided into two into an air heating chamber (18) and a chamber (18') with a double casing (1') and water-conducting heat exchange bodies (33) which are flow-connected to the double casing (1). An oil or gas burner (34) is then built onto the chamber (18').
