A dispensing pump includes a polymer compression spring assembly, base vents and a flow baffle. The dispensing pump includes a pump base, and a dispensing head having a piston stem. The polymer compression spring assembly includes a slotted tubular spring element and first and second loading cones received at opposing ends of the slotted tubular spring element. The venting ports allow air to escape when capping the container after filling and the flow baffle reduces or prevents the product from being pulled into the pump accumulator before residual air (headspace) has been evacuated from the container during the initial priming strokes.

Collapsible discs move towards or away from each other in embodiments of the disclosed technology by changing the angle of flanges which connect the two discs together. The flanges connect to each respective disc by way of one a fixed connection to one disc and a slidable connection to the other. The flanges slide into portals in the bottom disc and then extend along and into a hollow space therein the bottom disc. The flanges have a tip or multiple tips which is/are wider than a rest of an elongated length thereof which frictionally holds the flanges, and therefore, the discs in places until the discs are rotated causing the flanges to be pulled out from or pushed into the portals. This, in turn, causes the discs to move closer together or become further apart in embodiments of the disclosed technology.

A device for applying an axial force includes a longitudinal axis with a first compression surface located at a first end of the longitudinal axis and a second compression surface located at a second end of the longitudinal axis. A plurality of resilient members is positioned between the first compression surface and the second compression surface. A first resilient member is oriented with a first end proximate the first compression surface and a second end proximate the second compression surface. A second resilient member is oriented with a first end proximate the first compression surface and a second end proximate the second compression surface. The device has a compressed state and an expanded state where the first compression surface and second compression surface move in a direction of the longitudinal axis between the compressed state and the expanded state.

The vertical vibration isolation system of the present invention includes a bearing base, a guide rail assembly and a plurality of buckling elements. The bearing base has an upper platform that can move along a vertical direction. The guide rail assembly surrounds the bearing base and has a plurality of arc-shaped sliding channels. The top portion of each buckling element can move with the upper platform, while the bottom portion of each buckling element is slidably connected to the corresponding arc-shaped sliding channel. The vertical displacement of the upper platform would cause different degrees of buckling of the buckling elements and also induces sliding motion of the bottom portion of the buckling elements along the arc-shaped sliding channels. Accordingly, the vertical vibration isolation system can provide nonlinear restoring force by buckling and sliding mechanisms so as to exhibit vertical vibration isolation effect.

A spring for a check valve which can be used in particular in controllable vibration dampers, said spring comprising a flat main body with a first surface, a second surface and a centre point, and two or more spring arms, which cooperate resiliently with the main body and in the unloaded state protrude from the first surface or the second surface, the spring arms forming a free end and having a longitudinal axis that runs through the free end and tangentially to a circle about the centre point of the main body. The invention further relates to a check valve having a spring of this kind. In addition, the invention relates to a controllable vibration damper which comprises such a check valve, and to a motor vehicle having a controllable vibration damper of this kind.

The shock-absorbing buffer pad comprises an external compression body, an internal guide slot and an inserted adjusting component. The external compression body has a top part, a bottom part and a compression elastic component. The top part is configured with an inserting hole. The bottom part is located beneath the top part. The compression elastic component is connected between the top part and the bottom part. The compression elastic component has a folding part. When the top part is pressed, the compression elastic component will accumulate an inverse elastic force. The internal guide slot is formed on the bottom part of the external compression body and located inside the internal space of the external compression body. The internal guide slot has an inserting slot exposing upward. The interior of the inserting slot is formed with a stopping block. The inserted adjusting component has an inserting cylinder, which can be inserted into the inserting hole. The top surface of the inserting cylinder is positioned outside the inserting hole. The bottom part of the inserting cylinder is divided into multiple abutting walls corresponding to the stopping block.

A horizontal-motion vibration isolator utilizes a plurality of bent flexures to support an object to be isolated from horizontal motion. Each bent flexure includes a fixed end coupled to a base and a floating end which is cantilevered and coupled to the object being isolated. The arrangement of bent flexures allows the vertical height of the isolator to be reduced without compromising vibration isolation performance. Compressed springs or spring-like elements can be added to bear some of the weight of the object being isolated thus increasing the payload capacity of the isolator.
