Abstract:
PCT No. PCT/DE89/00636 Sec. 371 Date Apr. 8, 1991 Sec. 102(e) Date Apr. 8, 1991 PCT Filed Oct. 5, 1989 PCT Pub. No. WO90/04106 PCT Pub. Date Apr. 19, 1990.A double acting, self-priming bellows-type pump has a pair of bellows that work as displacement elements arranged each in a cylinder chamber mutually and synchronously interlocked by piston rod, so that at the same time as one bellows draws in, the other bellows delivers. One side of each bellows receives the medium to be delivered and the other side receives a medium under pressure. In at least the lower cylinder the bellows is connected to the top wall of the cylinder chamber so that the space around the outside of the bellows may be used for pumping fluid. A guide element is mounted in the lower chamber for supporting the bellows of the lower chamber and preventing the same from buckling during the alternating pressurizing and venting thereof during a pumping cycle.
