motion from a first normal position to a second actuated position is greater than the rate of return motion from the second to the first position an arrowrest is attachable to a support shaft for the arrowrest the support shaft is moveable between the first position and the second position as an arrow shaft discharges over the arrowrest the support shaft moves in one direction with less frictional resistance than in a return direction application_number US 22650299 A description the present invention may be embodied in a variety of different improved arrowrest structures such as may be used in association with an archery bow fig2 illustrates an arrowrest motion mechanism generally designated by the reference numeral 10 in accordance with a first preferred embodiment of the invention more specifically the arrowrest motion mechanism 10 employs a linear piston arrangement and includes a piston with reed valve assembly 12 such as attached via attachment arms 14a and 14b respectively and hinge point 16 to a rotatable arrowrest support shaft 20 whereto an arrowrest not shown such as known in the art may be attached in a manner such as also known in the art for ease of comprehension and clarity fig2 has been simplified by not showing the associated bracket and spring return such as are known in the art in the arrowrest motion mechanism 10 a piston traverses a length.
