The control chamber includes a control chamber inlet in fluid connection with the valve inlet side upstream of the controlled valve; a configuration providing a variable volume of the control chamber, a change in volume of the control chamber moving the movable valve body; and a first flexible wall allowing movement of the movable valve body. The first flexible wall provides an effective surface area against which the fluid pressure in the control chamber acts, the effective surface area decreasing upon movement of the movable valve body outward of the control chamber, the first flexible wall including a flex plate bearing against a curved surface.

Disclosed is a new compact clamp for sliding glass doors, which includes two jaws, left jaw and right jaw. One of the jaws has a damper formed by a double-effect damper with gas and oil technology, using a cylinder containing a front gas chamber and a rear gas chamber which are located at the ends of the cylinder, and a central oil tank, the gas chambers and the oil tank being separated by a blind piston and an annular piston, which are both leak tight. In the central oil tank is disposed a non-leak tight damping piston that is connected to a rod of the damper and divides the tank into two oil chambers.

A system for dampening vibrations in a vehicle is provided. The system includes a first heat exchanger core having a first plurality of fins, and a second heat exchanger core having a second plurality of fins. A vibration dampener is connected to the first and second heat exchanger cores. The vibration dampener extends through the first plurality of fins and through the second plurality of fins, while spanning the gap between the first and second heat exchanger cores. To accommodate the vibration dampener passing thorough the fins, the fins may be formed to define an enlarged aperture at a location where the vibration dampener passes through.

A coupling element prepared for fastening between a oscillatory body and a tower wall of a tower of a wind turbine in order to influence relative motion between the oscillatory body and the tower wall in order to thereby influence vibration behavior of the tower, comprising a first fastening section for fastening to the oscillatory body and a second fastening section for fastening to the tower wall in order to establish mechanical coupling between the oscillatory body and the tower wall via the coupling element, the coupling permitting relative motion between the oscillatory body and the tower wall, and the relative motion having a first motion direction, in the case of which the first and second fastening sections move toward each other, and a second motion direction, in the case of which the first and second fastening sections move away from each other, and the coupling element having a spring element for spring-elastic coupling between the first and second fastening sections, the spring-elastic coupling being described by a spring function and the spring element being designed in such a way that the spring function is substantially the same for the first and second motion directions and additionally or alternatively the spring element being designed in such a way that motion in the first motion direction leads to compression of a first spring section and to extension of a second spring section in the spring element and motion in the second motion direction leads to extension of the first spring section and to compression of the second spring section in the spring element in order to thereby match the respective spring functions for the first and second motion directions to each other.
