A spring configured to compress, expand, and provide a force is provided that includes a first ring, a second ring, a third ring, a first plurality of rolling elements arranged between the first and second rings, and a second plurality of rolling elements arranged between the first and third rings. When the spring is compressed, the first ring is configured to be elastically deformed in tension in a radially outwardly direction, and the second and third rings are configured to be elastically deformed in compression in a radially inwardly direction.

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.

A stoke simulator operable by an operation of a brake operation member that is operated by a driver, including: a housing: a movable member held by the housing so as to be movable relative to the housing, the movable member being connected to the brake operation member; a volume change chamber disposed forward of the movable member in the housing; and a plurality of elastic members disposed in the volume change chamber and capable of generating an elastic force in accordance with a movement of the movable member, at least one of the plurality of elastic members being a rubber-like member.

A suspension system for a vehicle and method for operating the same includes a shock absorber housing having a longitudinal axis, a spring disposed around the shock absorber housing, a retainer collar disposed around the shock absorber housing and an actuator engaged to the retainer collar. The actuator moves at least a portion of the retainer collar to move the spring in a direction corresponding the longitudinal axis. A switch generates a ride height position signal. A controller is coupled to the actuator and the switch. The controller controls a position of the actuator in response to the ride height position signal.

A shock-absorbing member wherein a columnar shaped-wood member is supported by a stopper bolt (a pressure-receiving member) at its axially one end side and is configured such that an impact load is applied to its axially other end side, and wherein the wood member is axially collapsed by the impact load applied thereto, thereby absorbing a portion of the impact load, and that may include a shaft (a reinforcement member) that extends in a direction intersecting with an axis of the wood member while being embedded in the wood member, so as to reinforce the wood member.

A telescopic column includes at least two telescopic elements movable with respect to one another between two end positions and at least one damper that is configured such that, prior to reaching at least one of the end positions, a force slowing the relative movement of the telescopic elements is exerted on at least one of the telescopic elements.

Utilizing a load generated by a non-linear spring, a spring constant of which increases as an amount of deformation increases, a measuring apparatus presses an indenter against a material surface and evaluates material characteristics. The measuring apparatus includes: an actuator that causes the non-linear spring to deform; a scale that measures the amount of deformation of the non-linear spring when the non-linear spring is deformed; and a controller that stores non-linear spring characteristic data for reciprocally calculating the amount of deformation and the load, and that drives the actuator based on the amount of deformation and the non-linear spring characteristic data such that the load reaches a target load.

An all plastic compression spring assembly includes a slotted tubular spring element formed from a tensile polymer material and first and second loading cones received at opposing first and second ends of the slotted tubular spring element. The loading cones are axially compressible toward each other 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.

Disclosed is a method of suppressing vibration of a mechanical device imposing upon at least one human hand holding the mechanical device. The method generally includes steps of preparing and assembling a fixing pin, an upper metal pad, an upper suppressing pad, a lower suppressing pad, and a lower metal pad to form a vibration-suppressing unit, and employing a fixing rack in collocation with an actuating part to fix the vibration-suppressing unit onto a massage body. In particular, the two adjacent upper vibration-suppressing washers are specifically designed to have different elasticity modulus, and the two spaced away and not adjacent upper vibration-suppressing washers have the same elasticity modulus, thereby suppressing and alleviating the vibration level to hand due to counterforce. Thus, the method achieves the effect of suppressing vibration, greatly alleviates counterforce imposing upon hand, and effectively avoiding fatigue, sore, chronical inflammation, or physical hurt.

An elastomeric compression spring for isolating vibrations between a first part and a second part. The first part is movable in a direction relative to the second part. The elastomeric compression spring comprises a tube elongated along a central axis of the tube. The central axis of the tube is perpendicular to the direction. The tube is configured to compress in the direction. The tube comprises an outer surface comprising an initial contact line configured to initially receive contact from the first part. The tube further comprises at least one load tuning feature in the outer surface, parallel to the central axis, and circumferentially spaced apart from the initial contact line. The at least one load tuning feature creates a localized change in a thickness of the tube and a stiffness of the elastomeric compression spring at the at least one load tuning feature.
