ABSTRACT:
The invention proposes a fluid handling device, which may be a pump, in which arrangements are provided to make the device able to handle high pressure of more than one thousand atmospheres and able to seal at such high pressure for a considerably long life time of the device. For the obtainment of such a performance, a piston shoe arrangement has a part-ball formed portion with an outer face which is guided on a cylindrical inner face, while the piston shoe at the same time pivots around a center which is located in the pistons-head. Sealing means are provided to faces of plates, membranes or pistons to reduce leakage or to reduce the negative effects of deformations under high pressures. In this relation a thrust body may be axially moveably provided in a thrust chamber and obtain thereby a novel and effective sealing of membranes and faces.
