A spring for use in conjunction with a vehicle, in particular a leaf spring (1), preferably a parabolic spring, has a single-part spring leaf (12) made of steel, in particular spring steel, having a central region (2) and two adjoining edge regions (4a, 4b), wherein the edge regions (4a, 4b) each have an end region (5a, 5b), the end regions (5a, 5b) can each be connected to a chassis in a stationary manner via a rolled eye (11), and the total length of the spring when installed on the vehicle is substantially unchangeable in all load states. In the unloaded state, the spring leaf (12) has two bending sections (13, 14), which each have a curvature with a curvature direction, wherein the curvature directions of the two bending sections (13, 14) are opposed, and the two bending sections (13, 14) merge into each other in the region of a turning point (15). The first bending section (13) is a vertical spring section and runs from the end region (5a) of the first edge region (4a) via the central region (2) to the turning point (15). The second bending section (14) is a horizontal and vertical spring section and runs from the turning point (15) to the end region (5b) of the second edge region (4b).

The disclosure provides a mount bracket which is configured for a fan. The mount bracket includes a button plate, a frame and a plurality of vibration-absorbing components. The button plate is mounted with a motor mount. The frame surrounds the button plate, and the frame has an inner lateral surface and an outer lateral surface. A plurality of fixing structures protrude from the outer lateral surface of the frame. The inner lateral surface of the frame and an outer lateral surface of the button plate form an annular gap therebetween. The vibration-absorbing components are spaced apart from each other and located in the annular gap, and the vibration-absorbing components are located between and connected to the outer lateral surface of the button plate and the inner lateral surface of the frame.

An illustrative example spring includes a curved shape body having a length. The body includes a cavity that extends along at least a majority of the length. The body has a cross-section across the length that is different at a plurality of locations on the body along the length.

A steering assembly having an inner steering member; an outer member, where the inner steering member is adapted to translate relative to outer member; and a bearing component disposed around a portion of the inner steering member, where the bearing component includes a bearing having a unitary substrate and a polymer layer overlying the substrate, where the bearing has a generally arcuate shape and is adapted to support the inner steering member disposed in the outer member, where the bearing has a support region for supporting an inner steering member, and a plurality of feet comprising a first foot and second foot spaced apart from each other such that the support region extends there between, and where the first and second feet extend in radial direction beyond the support region such that upon assembly between inner steering member and outer member, wherein the bearing exerts a force against the inner steering member.

A mass flow controller includes an inlet, a flow path in which fluid passes, a mass flow sensor configured to provide a signal corresponding to mass flow of the fluid through the flow path; a control valve configured to regulate a flow of the fluid out of an outlet of the mass flow controller; and a passive damping system coupled to the control valve and configured to dissipate fluid flow induced vibrations introduced by the control valve assembly. The passive damping system includes a damping pad between a receiver section of a valve base and a diaphragm backer. The passive damping system can also include a damping washer. The passive damping system can include one or more plunger balls between the damping pad and the valve base or one or more wave springs.
