摘要： A plunger and cylinder assembly for the fluid end of a reciprocating pump. The assembly comprises a traveling cylinder, a stationary plunger, and an optional sleeve secured to the traveling cylinder in a detachable manner. The traveling cylinder is displaced along its axis by a thrust component and acts cooperatively with the stationary plunger to create a pressure change in the reciprocating pump.

摘要： A locking apparatus for a hydromechanical spring energy store drive for actuating a medium-voltage or high-voltage circuit breaker is disclosed, the spring energy store drive includes a working piston, which is guided in an axial cutout in a pressure housing or working cylinder, and a spring energy store arrangement. The locking apparatus includes a first pressure region and a second pressure region, which are under elevated pressure when the circuit breaker is closed, and a third pressure region, which is unpressurized. The latching bolt can be arranged perpendicular to the working piston, via a latching apparatus, which can be arranged on a side of the latching bolt, which is to point towards the working piston and via the spring energy store arrangement, which is to be pushed away from the working piston.

摘要： A one-piece piston having an investment or other permanent or non-permanent mold/die precision cast piston crown, rod flange and piston skirt. The piston crown has a relative constant thickness, a flange requiring minimal machining and a skirt providing for a wall with a support against the angular shifting of the piston. This improves the distribution of heat within such crown and the angular stability of the piston wall at the piston rod connection.
