An accumulator assembly includes a vessel having an upper portion and a lower portion. The accumulator assembly includes a flexible membrane extending between the upper portion and the lower portion. The membrane may divide the vessel into a first interior chamber and a second interior chamber. The accumulator assembly includes a receptacle located proximate the vessel. The receptacle may be in fluid communication with the second interior chamber. The accumulator assembly includes a plunger located at least partially within the receptacle.

As disclosed herein, the viscoelastic performance of boron nitride nanotube (BNNT) materials may be enhanced and made into useful formats by utilizing purified BNNTs, aligned BNNTs, isotopically enhanced BNNTs, and density controlled BNNT material. Minimizing the amounts of boron particles, a-BN particles, and h-BN nanocages, and optimizing the h-BN nanosheets has the effect of maximizing the amount of BNNT surface area present that may interact with BNNTs themselves and thereby create the nanotube-to-nanotube friction that generates the viscoelastic behavior over temperatures from near absolute zero to near 1900 K. Aligning the BNNT molecular strands with each other within the BNNT material also generates enhanced friction surfaces. The transport of phonons along the BNNT molecules may be further enhanced by utilizing isotopically enhanced BNNTs.

A support kit having a support base and a pole mountable to the support base is provided. A mounting seat having a square cross-section and configured to receive a lower end of the pole is formed in the support base. The mounting seat has a bottom surface through which a hole is formed. The hole is coaxially connected to a nut seat formed in the support base. The pole has a square section hollow profile interference-fittable to the mounting seat or a telescopic structure with a lower member that has a smaller cross-section than a cross-section of the mounting seat and a bottom portion provided with a threaded pin, through which the pole is screwable to a threaded nut arranged within the nut seat.

A shock absorbing device according to one embodiment includes an elastic member and an attenuation device. The elastic member is compressed by a force transmitted from the exterior of a vehicle through a front grill which is a vehicle exterior component, and returns the front grill to the vehicle exterior by means of the restoration force against the compression. The attenuation device attenuates the speed of the front grill when the front grill is being returned by the restoration force of the elastic member.

A core material for a shock insulation support, comprising, in parts by weight: steel shot of 150-300 parts, zirconia particles of 50-150 parts and rubber particles of 50-100 parts. Further provided are a shock insulation support comprising the core material, and a preparation method for the shock insulation support. The core material for a shock insulation support, and the shock insulation support dissipates earthquake energy by means of a dry friction energy dissipation mechanism, having high damping and excellent shock insulation performance.

Disclosed herein is a process suitable for constructing a multiple stage air shock. The multiple stage air shock is unique among shocks in that the multiple stage design possesses qualities not available to other shock absorbers. The process includes a means for determining the compressed and extended lengths of the air shock based on the lengths of the parts for each stage. This means refers to one methodology and offers the air shock an extended length that is greater than twice its compressed length, an optimized extended length, and a construction capability based on adding stages. In particular, the extended length-compressed length relationship is a quality inherently unobtainable by current shock absorbers. The process also includes a means of determining the spring rate. This means refers to a second methodology and offers the capability to both set-up the air shock with a relatively linear spring rate and make the relatively linear spring rate more linear.

Damper includes a housing having proximal and distal ends, a first attachment point proximate the distal end of the housing, a rod having proximal and distal ends at least partially disposed within the housing and moveable relative to the housing between an extended position and a compressed position, a second attachment point proximate the proximal end of the rod, a piston joined to the rod within the housing proximate the distal end of the rod, the piston including a bypass groove having a flow area defined therein to allow fluid to flow from a first side of the piston to an opposing side of the piston, and a first washer disposed proximate a first end of the piston and at least partially covering the flow area of the bypass groove.

The invention relates to a suspension for a mower comprising a stationary and a movable part and one or more cutting units. The moveable part is suspended to the stationary part via a hydraulic actuator. An agricultural mower, an agricultural vehicle and uses are also disclosed.

An inner tube moves axially between an outer tube and a support, all of which are concentrically arranged, to a desired telescopic position, relative to the outer tube and the support, and can be locked in the desired telescopic position by applying radial force between the support and the inner surface of the inner tube. The radial force generates a frictional force acting on the inner surface of the inner tube, which resists longitudinal movement of the inner tube. A bicycle actuator cable is coupled to an actuator connector for a tension-controlled actuator by a bicycle cable connector which has a fixed longitudinal position on the bicycle actuator cable. The bicycle cable connector is longitudinally consistently removably repeatably interengageable with the actuator connector to maintain longitudinal alignment of the bicycle actuator cable with the actuator through repeated engagement and disengagement of the bicycle cable connector and the actuation connector.
