Methods and systems are provided for a flexible support for a vehicle. In one example, the flexible support is formed of a composite material and configured to surround a vehicle component and absorb oscillations generated by the vehicle. The composite material may be a mixture of aluminum particles dispersed in an elastomer matrix.

Control valves and cages that are adapted to reduce flashing and cavitation. A cage for use with a control valve having an inlet, an outlet, and defining a flow passage between the inlet and the outlet. The cage includes a generally cylindrical body and having a central bore, an upper portion, and a lower portion and an inner wall, an outer wall, and an intermediate wall disposed between the inner wall and the outer wall. The inner wall includes an inlet opening and the outer wall including an outlet opening. The inner wall, the outer wall, and the intermediate wall cooperate to define a portion of the flow passage that extends from the inlet opening, through the cage along the inner wall, along the intermediate wall, past a terminal portion of the intermediate wall, along the outer wall, to the outlet opening.

A natural gas pumping system that includes six reciprocating compressor cylinders, the reciprocating pistons of the six compressors having cycles offset by 60 degrees one from another.

A line element includes an inner element, an outer element surrounding the inner element, and a damping element arranged between the inner element and the outer element. The damping element can be made, for example, of knitted wire fabric or a stripwound hose. The damping element can be made in particular of a more easily wearing material than the outer element and/or the inner element, for example of copper.

Provided is a hydraulic unit of a brake system including a housing; an oil supply part configured to supply oil to the housing; an oil discharge part configured to discharge the oil, supplied to the housing through the oil supply part, to the outside of the housing; and a piston movably mounted on the housing, and configured to open and close the oil supply part and the oil discharge part.

A subsea tubular system comprises extended sections of a first material and interposed sections of a second, different material that aids in damping vibration resulting from subsea dynamic conditions such as current. The vibration damping sections may make up a portion of the overall system significantly less than the sections of the first material. The number, length, and positions of the vibration damping sections may be selected based on factors such as the diameter, overall length, profile, and so forth. The system may be used as a riser or other conduit for the production of minerals such as oil and gas.
