Abstract: A valve trim that is configured to abate noise in a control valve. These configurations may include a cage with a flow path that has interior and exterior openings. The cage may also have a bore to receive a closure member or “plug.” This plug can travel longitudinally to change parameters of flow through the control valve. In one implementation, the exhausts of flow paths with adjacent inlets are offset or spaced from another. In one implementation, the exterior openings vertically offset. However, other designs may adopt combinations of radial, helical, or angular offsets as well. This feature can prevent mixing of flow from jets that are in the same inlet plane. This feature, in turn, can reduce jet-to-jet interactions that may abate noise. Use of additive manufacturing may be useful (or even necessary) to create these parts within certain design envelopes because these techniques can create the unique flow geometry within a unitary or monolithic body.

Abstract: A solenoid valve has a valve plunger which is guided in a passage bore of a valve housing. The valve plunger with its valve closing element is held in a basic position by a restoring spring. The basic position opens up a valve passage in a valve seat. The valve plunger is arranged between an inlet and an outlet channel in the valve housing. A magnet armature provides actuation of the valve plunger. An inlet chamber is connected to the inlet channel between the passage bore and the valve seat. The valve plunger protrudes into the inlet chamber by way of a step section. As a result of being hydraulically impinged on by the pressure medium of the inlet channel an axial force is generated on the valve plunger that acts oppositely to the closing direction of the valve plunger.
