    摘要: An actuator arranged to be movable between an extended condition and a compressed condition and being biased to an intermediate condition between and distinct from the extended condition and the compressed condition. The actuator includes a damping device arranged to define the damping coefficient of the actuator. The damping device is arranged to provide a relatively low damping coefficient when the actuator is in a first condition distinct from the intermediate condition, and a relatively high damping coefficient when the actuator is in a second condition, the second condition being distinct from the first condition and being equal or adjacent to the intermediate condition

    摘要: The present invention provides a three position hydraulic piston assembly for a gear ratio change mechanism for a transmission exhibiting reduced gear shift noise. The three position hydraulic piston assembly includes a master piston and motion retarding assemblies that act near both travel limits of the master piston. The master piston includes symmetrical passageways that provide hydraulic fluid flow to small chambers at each end of the piston that are closed off as the piston approaches its travel limits. Hydraulic fluid trapped in the chambers decelerates the piston and is bled off through an orifice allowing the piston to reach its travel limit and quickly and quietly engage a gear ratio.

    摘要: A multi-position control cylinder for hot runners of injection molding machines is disclosed. This multi-position control cylinder has a multi-stage hole formed in a unit body, a first cylinder seated in the lower part of the multi-stage hole, and a first piston set in the first cylinder. In addition, a second cylinder is seated in the multi-stage hole at a position above the first cylinder, with a second piston set in the second cylinder. A valve pin is coupled to the second piston using a valve pin coupling member such that the valve pin extends downward from the second piston while passing through the first piston, with the lower portion of the valve pin inserted into the upper portion of the first piston. An anti-vacuum gap is formed between the first piston and the valve pin coupling member. A cylinder head covers the top of the multi-stage hole at a position above the second piston. This multi-position control cylinder has a simple construction, accomplishes a reliable operation, and easily increases the number of cylinders seated in the multi-stage hole by seating a desired number of additional cylinders with pistons in the multi-stage hole.
