A shuttle valve includes: a first valve body; a second valve body, a first control-pressure-charged surface and a second control-pressure-charged surface of the first valve body being larger than a third control-pressure-charged surface and a fourth control-pressure-charged surface of the second valve body, a first control pressure from a first inlet pressure port being applied to a first valve body first side, the first control pressure from a second inlet pressure port being applied to a first valve body second side, a second control pressure from a third inlet pressure port being applied to a second valve body first side, the second control pressure from a fourth inlet pressure port being applied to a second valve body second side, a first control pressure acting on a first control-pressure-charged surface and a second control-pressure-charged surface, and the second control pressure acting on a third control-pressure-charged surface and a fourth control-pressure-charged surface.

An electromagnetic drive for implementing a linear motion includes an electromagnet having a coil, a core and an armature able to move linearly along a symmetrical axis of the core, wherein an air gap is formed between the core and the armature. With the objective of providing for simple, compact, cost-effective and flexible use of the electromagnetic drive in high-pressure systems as well as a concurrent exact positioning of the piston at any given position at optimized extension speed, it is provided for the air gap to exhibit a base and two limbs running symmetrically to the symmetrical axis as well as an essentially frustoconical cross-section in longitudinal section and for the limbs to be arranged relative to the symmetrical axis of the core so as to form an angle &#x3b1;.
