A spring-loaded ball valve includes a spring, a first pin, a second pin, and a handle. The spring is configured to apply pressure to the first pin and second pin when the ball valve is in both the fully open and fully closed positions. The spring applies maximum torque when the ball valve is in the fully open or fully closed position to ensure the valve remains in the fully open or fully closed position.

Embodiments of the present invention generally relate to a novel system, device, and methods for providing an isolator for components and instrumentation to isolate vibrations, shock, static or quasi-static loads, thermal loads, and electrical currents. The novel isolator has an asymmetrical shape, experiences uniform motion under quasi-static loading, and reduces the effective modal mass across a range of frequencies. The novel isolator outperforms conventional vibration isolators in terms of cost, schedule (manufacturing time and lead time), heat dissipation, and performance.

A gas spring and gas damper assembly includes a gas spring and a gas damper. The gas spring includes a flexible spring member with opposing end members secured thereto and at least partially defining a spring chamber. The gas damper includes an inner sleeve that is at least partially received within one of the end members and at least partially forms a damping chamber. A damper piston assembly is received within the damping chamber and secured to the other of the end members. An elongated damping passage fluidically connects the damping chamber and the spring chamber. Suspension systems and methods are also included.

A composite structure includes a thermoplastic material and axial fibers and radial fibers arranged within the thermoplastic material. The thermoplastic material can define a substructure of the composite structure. The fibers can be continuous and/or discontinuous fibers. The substructure can be a first substructure and the composite structure can further include a second substructure. Opposing ends of the first substructure and the second substructure are bonded with one another to form a tubular structure. The composite structure can exhibit enhanced damping characteristics such as having a damping coefficient greater than 0.5 lbf s/in. In some cases, this can limit vibrations of the tubular structure to less than 5.0 m/s2.

A spring assembly includes a first coil spring and a second coil spring. The second coil spring includes a first winding portion and a second winding portion. The first winding portion includes a plurality of windings from a first winding to at least a second winding. The second winding portion is a portion except for the first winding portion. An outer diameter of each of the plurality of windings of the first winding portion is smaller than an outer diameter of each of at least one winding of the second winding portion. Each of the plurality of windings of the first winding portion includes the substantially same outer diameter.

A method of manufacturing an elevator safety spring is provided. The method includes determining a plurality of dimensional parameters of the elevator safety spring. The method also includes selecting a plurality of dimensions within the dimensional parameters. The method further includes manufacturing the elevator safety spring based on the selected parameters, the elevator safety spring having an I-beam cross-section.

The present application provides a superimposed opposing wave spring that has a plurality of superimposed-layer wave spring units, wherein each layer in each superimposed-layer wave spring unit is formed by spirally bending around an axis into a wave shape, and waveforms of the respective layers in each superimposed-layer wave spring unit are arranged to overlap each other. At least one connection spring part, which connects two adjacent superimposed-layer wave spring units that are stacked one above the other, so that the two adjacent superimposed-layer wave spring units respectively have a first wave trough and a second wave crest that are abutting each other with opposing apexes, and respectively have a first wave crest and a second wave trough that are arranged across from each other in an upper position and a lower position.

A wind turbine is provided, including a container, a fluid which is arranged inside the container, and a damping body which is arranged inside the container, which is immersed in the fluid, and which is configured to move inside the container, wherein the fluid and the damping body are configured to damp oscillations of the wind turbine. A damper system is provided that on the one hand the fluid damps, e.g. by sloshing, and on the other hand the damping body damps by moving at least partially through the fluid.

An assembly has a wheel and a nonpneumatic tire. The nonpneumatic tire includes a plurality of helical springs. Each helical spring includes a first end portion, a second end portion, and an arching middle portion. Each helical spring being is interlaced with at least one other helical spring thereby forming a laced toroidal structure extending about an entire circumference of the nonpneumatic tire. The toroidal structure supports an entire load placed on the nonpneumatic tire. The plurality of helical springs are constructed of a predetermined material that maintains strength and ductility down to 17 K.
