摘要： A hydraulic drive for executing a linear movement includes a motor, a pump, a lifting cylinder having the one linearly movable piston and a cylinder housing with at least one first connection and at least one second connection, a spring arranged such that the piston can be extended or retracted when the spring is in the relaxed state, and at least one first valve with which the first connection and the second connection of the cylinder housing can be fluidly connected. At least one second valve connected in parallel with the first valve is further provided, wherein the first valve has a maximum volumetric throughflow which is greater than the maximum volumetric through-flow of the second valve.

IPC分类号： F16K31/04
摘要： A valve drive with a snap function includes a rotary drive input, a lead screw connected to or formed by the rotary drive input, a slide in threaded engagement with the lead screw to form a screw thread, the slide being mechanically connected or connectable to a valve body and being movable in the direction of a longitudinal axis. A bearing housing is provided in which the lead screw is mounted so as to be rotatable about the longitudinal axis and stationary in the direction of the longitudinal axis. The bearing housing is held against a displacement along the longitudinal axis by a releasable locking device, countering the preload force of a snap spring.

摘要： 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 α.
