A damping stopper is interposed between two members axially displaced relative to each other and is provided with an elastic body which, when the interval between the two members decreases, is axially compressed by the two members and expands radially outward. In the elastic body, a second member suppressing the expansion is located in one axial region and attached to the outer periphery. When axially compressed by the two members, the elastic body expands while receiving resistance by the second member. The expanding elastic body contacts the side wall of one of the two members.

A dispensing pump (1000) includes a polymer compression spring (1048), base vents (1060) and a flow baffle (1092). The dispensing pump includes a pump base (1002), and a dispensing head (1004) having a piston stem (1034). The polymer compression spring assembly includes a slotted tubular spring element (1048) 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.

A damper is disposed in at least one of a space between a supported member and a supporting element or a space between the supported member and a supporting member. The damper includes a cushioning member and a protecting member. The cushioning member is configured to relax stress applied to the supported member that is supported by the supporting member together with the supporting element. The cushioning member includes a facing portion that faces the supported member, an opposite portion that is opposite to the facing portion, and a side surface portion that is located between the facing portion and the opposite portion. The protecting member is disposed on the side surface portion to cover the cushioning member from an outside of the cushioning member.

An impact buffer has a retaining part for fitting to a loading ramp, a stop part for a vehicle to be loaded at the loading ramp to strike, and a buffer part for cushioning the stop part against the retaining part. The stop part is supported on the retaining part with at least one pivot lever.

A multi-tiered recoiling energy absorbing system has an upper impact surface that is exposed to percussive impact. At least one energy absorbing layer is positioned below or inside the upper impact surface. The energy absorbing layer includes one or more energy absorbing modules. At least some of the modules are provided with one or more energy absorbing units that extend from an upper platform. Several of the energy absorbing units are provided with a flexible wall that extends from the upper platform. A lateral reinforcement member secures the energy absorbing units to prevent them from splaying. The energy absorbing units at least partially absorb energy generated by an impacting object due to the flexible wall bending inwardly or outwardly and recoiling nondestructively after single or multiple impacts to its un-deflected configuration.

A bumper for a closure, such as a tailgate, acts between the tailgate and a frame to bias a striker in to engagement with a latch. The bumper is moved to a retracted position during closing to reduce the force needed to close the tailgate. After latching, the bumper is conditioned to an extended position to assert the bias between the tailgate and frame.

A damper is disposed in at least one of a space between a supported member and a supporting element or a space between the supported member and a supporting member. The damper includes a cushioning member and a protecting member. The cushioning member is configured to relax stress applied to the supported member that is supported by the supporting member together with the supporting element. The cushioning member includes a facing portion that faces the supported member, an opposite portion that is opposite to the facing portion, and a side surface portion that is located between the facing portion and the opposite portion. The protecting member is disposed on the side surface portion to cover the cushioning member from an outside of the cushioning member.

A bracket assembly includes a first bracket arranged along a damping axis and having a clevis body, a second bracket, and a vibration isolator including an elastomeric body. The second bracket is arranged along the damping axis and has a clevis portion and a mount portion. The clevis portion slidably receives the clevis body of the first bracket. The elastomeric body is arranged axially between the first bracket and the second bracket and is fixedly arranged between the clevis portion of the second bracket and the clevis body of the first bracket through an on-axis load path and through an off-axis load path extending through the bracket assembly. Actuator arrangements and methods of damping vibrational forces are also described.

A spring configured to be fixed to a housing and nested within a dial that is rotatable about the spring. The dial has a plurality of spaced apart inwardly facing teeth that are adjacent the spring. The spring is configured to facilitate rotation of the dial about the spring. The spring includes a central body having at least one anchor configured to connect the spring to the housing. The spring also includes at least one arm having a first end connected to the central body. The spring also includes a second end of the arm that is connected to a bulb. The bulb can be enclosed and include an exterior surface with a node that is on distal from the central body. The node is sized to fit in a space between adjacent teeth. The enclosed bulb biases the node toward the spaces between the teeth.

An all plastic compression spring assembly includes a slotted tubular spring element formed from a tensile polymer material and upper and lower loading cones received at opposing upper and lower ends of the slotted tubular spring element. The upper loading cone may be axially compressible towards the lower loading cone within the slotted tubular spring element whereby the slotted tubular spring element radially expands in tension to create an opposing radial contraction force, and in turn, an axial extension spring force. When released, the spring element elastically returns to its normal at rest shape, returning the cones to their normal at rest positions. In some dispenser configurations, the lower loading cone may be stationary or fixed within the dispensing head and the upper loading cone may be downwardly compressible toward the lower loading cone by movement of a nozzle head.
