PCT No. PCT/SE94/00378 Sec. 371 Date Mar. 21, 1996 Sec. 102(e) Date Mar. 21, 1996 PCT Filed Apr. 27, 1994 PCT Pub. No. WO94/28316 PCT Pub. Date Dec. 8, 1994A purification apparatus for removing gases and water from a fluid in a system, including a tank which has an expansion chamber for fluid in the system. A pump pumps the fluid in a circulation circuit of which the purification apparatus is an integral part. A closed chamber has a fluid-free upper part and contains a level-sensing device which controls flow of fluid to the closed chamber. The fluid-free upper part of the closed chamber is connected with a vacuum pump which sucks gases from the closed chamber and creates a lower pressure in the closed chamber than at an outlet of the apparatus. A pressure-generating device sucks fluid from the closed chamber. |
