Abstract: A bolsterless bogie for rail vehicles has at least one link which is directly connected to the bogie frame and the rail vehicle center pivot by means of wear-free rubber joints and connecting pins. Rubber buffers limit the transverse motion between center pivot and bogie frame; vertical forces are transmitted by air-spring bellows arranged in the vehicle center plane between the underframe and the bogie side sill, and stops effective in the travel direction are provided between center pivot and bogie frame.

Abstract: An apparatus for venting and deaerating a liquid circuit, such as the coolant circuit of an internal combustion engine, has a surge tank with an air-side port and a liquid-side port. Installed in the air-side port is a tube, through one end of which liquid to be deaerated is admitted at a certain velocity. The tube has a longitudinally extending lateral slot through which the admitted liquid is discharged; opposite the slot is located a baffle onto which the discharged liquid impinges over a large surface area. This causes even small air bubbles to be liberated from the liquid so as to remain in the air-side part, whereas the deaerated liquid runs off the baffle and into the liquid-side part of the surge tank.
