Abstract
An equalization tank for a cooling liquid which is subdivided by an essentially perpendicularly disposed interior partition wall into a prechamber and into a suction-discharge chamber; the vent lines which are connected with the cooling water outlet of the cooling water jacket of the engine and with the heat-exchanger thereby terminate in the prechamber whereas the auxiliary return line leading to the circulation pump for the cooling liquid terminates in the suction-discharge chamber; the partition wall is thereby also provided with a connection located near the tank bottom for cooling liquid, low in air or gas bubbles, as also with a vent connection between the prechamber and the suction-discharge chamber which is located near the tank ceiling.
Claims19
An equalization tank for a cooling liquid which on its inlet side is adapted to be connected with at least two vent lines and on its discharge side with at least one auxiliary return line, characterized in that an interior generally upright partition wall means provides a subdivision of the equalization tank into a prechamber means and into a suction-off chamber means, the vent lines terminating in the prechamber means and the auxiliary return line in the suction chamber means, and the partition wall means being provided with a connection means located near the tank bottom for cooling liquid low in gas bubbles and with a vent connection means located near the tank ceiling between the prechamber means and the suction chamber means, a fill-in pipe connection for cooling liquid, in which the vent line adapted to be connected with the heat-exchanger means is connected with the fill-in pipe connection, the fill-in pipe connection terminating in the prechamber means, a pressure equalization valve means being interconnected between the tank interior space and the atmosphere, the pressure equalization valve means being connected with the suction-off chamber means, a shielding means being arranged above the opening of the auxiliary return flow line terminating in the suction-off chamber means, the shielding means being inclined to the horizontal plane and being provided in its upper portion with a vent connection means between the section of the suction-off chamber means located on its bottom side and the section of the suction-off chamber means located on its top side.

An equalization tank for volume equalization and air separation of a liquid heat carrier flowing through a circulating system, especially for a circulatory system for combustion engine cooling spaces and the like, comprising:
- separation chamber means,
- air chamber space means arranged above said separation chamber means,
- venting means communicating the air chamber space means and the separation chamber means for accommodating escape of entrapped air from the liquid flowing through the separation chamber means to the air chamber space means,
- the separation chamber means being constructed and arranged to form liquid-air separating means and including a plurality of separate separation chambers, a first of the separation chambers including an inlet portion coupled with a separation flow entrance leading from the circulating system and an outlet portion coupled direcly with a second of the separation chambers, the outlet portion being constructed and arranged to permit passage therethrough of at least a substantial portion of the flow of liquid through the first separation chamber to the second separation chamber,
- the outlet portion being provided with a connection means for liquid enriched with bubbles between the first separation chamber and the second separation chamber and a connection means for liquid low in bubbles between the first separation chamber and the second separation chamber, the connection means for liquid enriched with bubbles being located geodetically between the connection means for liquid low in bubbles and the air chamber space means.
