A handlebar vibration damping assembly (HVDA) () that is used in combination with a conventional two-wheeled vehicle's handlebar () assembly having a right grip (), a left grip () and a center section (). The HVDA () is comprised of a weight () having a first end (), a second end (), an outer surface () and a cavity () that extends into the second end (). A spring () has a first end () and a second end (), with the first end () inserted into the cavity () on the weight's second end (). In order to maintain the HVDA () within the handlebar, a bolt () having a head () and a tip () along with an insert () having a bore (), an insert nut () and a second nut () are utilized. The second end () of the spring () extends into the insert bore (). Once the HVDA () is securely placed within the handlebar () the weight () can vibrate in any excitable direction 90-degrees of the centerline of the handlebar and can oscillate at different frequencies.

An intake or exhaust valve for an internal combustion engine has a rocker arm with a pivot between its ends, one end of which is engaged by the pushrod, and the other end engages the valve stem. An adjustable stop has two positions for the rocker arm pivot; a rest position where there is no movement of the pivot, and an upper lock position where the pivot moves in response to the pushrod, and there is a reduction in the opening of the valve. A progressive rate spring compresses as the pivot moves towards the upper lock position, thereby modulating valve opening for relatively slow start (or stop) of valve stroke with accelerating (or decelerating stroke), as the progressive rate spring compresses (or expands). Relatively thinner and thicker Belleville springs are used in series to produce a progressive rate spring. The lock position of the pivot elevated above the rest position is determined by a hydraulic block trapping oil in a closed chamber. One or more intermediate lock positions can be provided by varying the available volume of the closed chamber. An inner sleeve is rotated to obstruct one or more holes for fluid passage and an outer sleeve moves longitudinally to hit hydraulic block when an end passes the highest of such holes.

A twin tube shock absorber having inner and outer tube with an annular reservoir between the tubes. A piston in the inner tube divides the inner tube into an upper chamber and a lower chamber and valves through the piston control stiffness of the shock absorber. An acceleration sensitive valve assembly mounted in the base valve makes the shock absorber &ldquo;soft&rdquo; upon downward acceleration of the wheel of the vehicle in which the shock absorber is mounted. The valve assembly includes a port for fluid communication between the lower chamber and a conduit, and an inertial mass blocking the port in a port-closed position and not blocking the port in a port-open position. The inertial mass is normally in a lower port-closed position in absence of downward acceleration of the tubes of the shock absorber. Upon downward acceleration of the tubes, the inertial mass moves upwardly toward a port-open position where fluid flow through the port is not blocked.

Acceleration sensitive twin tube shock absorber

An acceleration sensitive shock absorber has a tubular housing and a piston assembly in the housing dividing the housing into an upper chamber and a lower chamber. The piston is connected to the wheel of a vehicle and the housing is connected to the chassis of the vehicle. Fluid can pass between the upper and lower chambers with a restricted flow rate during either extension or compression of the shock absorber. There is a first port for providing fluid flow from the lower chamber to the upper chamber upon downward acceleration of the wheel. A movable inertia valve in the piston assembly opens the first port when acceleration of the wheel of the vehicle is greater than a predetermined magnitude for increasing flow between the chambers. In addition, there is a first orifice downstream from the first port for creating hydraulic pressure which biases the inertia valve in an open position in response to fluid flow between the chambers. There is a second port or passage for providing fluid flow from the upper chamber to the lower chamber. A second orifice upstream from the second which provides hydraulic pressure to decrease the response time during compression.

Flow sensitive, acceleration sensitive shock absorber

An acceleration sensitive shock absorber has a tubular housing and a piston assembly in the housing dividing the housing into an upper chamber and a lower chamber. The piston is connected to the wheel of a vehicle and the housing is connected to the chassis of the vehicle. Fluid can pass between the upper and lower chambers with a restricted flow rate during either extension or compression of the shock absorber. There is a first port for providing fluid flow from the lower chamber to the upper chamber during downward acceleration of the wheel. A movable inertia mass in the piston assembly opens the first port during downward acceleration of the wheel of the vehicle for increasing flow between the chambers. A pocket beneath the inertial mass applies sufficient pressure to the inertial mass to retain it in a port-open position during fluid flow after acceleration has decreased. There is a fluid turning vane for applying sufficient fluid pressure to the inertial mass to maintain the mass in a port-closed position when acceleration of the wheel has decreased or stopped. In addition there is a pressure relief system including a port from the pocket and a pressure relief valve for relieving fluid pressure in the pocket, thus minimizing mechanical noise as the inertial mass moves toward the port-open position.

Flow sensitive acceleration sensitive shock absorber with added flow

A modified McPherson strut has inner and outer tubes which are connected to the wheel of a vehicle. A piston within the inner tube is connected to a piston rod which is connected to the body of a vehicle. The piston divides the inner tube into an upper chamber and a lower chamber, with the upper chamber being in fluid communication with an annular gallery formed between the inner and outer tubes. Normal damping is provided by fluid passing though metering valves in the piston between the upper and lower chambers. The strut also includes an accumulator gallery inside the bottom of the outer tube with a foot valve for restricted fluid flow from the lower chamber into the accumulator gallery and essentially unrestricted flow from the accumulator gallery back into the lower chamber. An acceleration sensitive inertial mass in a bypass passage is normally closed and opens upon upward acceleration of the tubes during strut compression. This bypasses fluid directly from the lower chamber into the accumulator gallery, making the strut 'softer.' Similarly, a rebound inertial mass in another bypass passage opens a valve when the downward acceleration of the tubes is greater than a selected magnitude. A restricted flow path is provided downstream from the rebound inertial valve opening for maintaining the inertial mass in a port-open position in response to fluid flow past the rebound inertial mass.

An apparatus for producing braided reinforcement for tubular conduits such as hose is disclosed. The reinforcement is characterized by a three over, three under braid pattern. The apparatus comprises a Maypole type braider wherein each driver of the braider includes six pockets to accommodate carrier spindles, and the number of carriers is three times the number of drivers. The invention provides a braided product which can be produced at lower cost with increased output.
