Abstract: A ratcheting-type, rotor controlled, continuously variable transmission machine wherein the circumferential length of a cross-sectional profile of a body of the rotor is substantially constant, and the maximum positive swivel angle of the body is substantially equal in magnitude to the maximum negative swivel angle of the body.

Abstract: A controller of the present invention is provided for valve to be connected thereto. The controller is used for executing rotation and movement motion so as to operate the stem of the valve and to control connection conditions of the valve. As such, the valve assembled with the controller can be controlled and switched automatically. Cost of management of factories is minimized.

Abstract: A constant power mechanical transmission with seamless, ripple free, infinitely variable torque multiplying outputs comprises an input shaft and an output shaft. The input shaft is coupled to a pair of oscillating levers whereby rotation of the input shaft causes oscillation of the oscillating levers in opposite directions. The oscillating levers are linked to the output shaft with one-way clutches in order to cause rotation of the shaft upon movement of the oscillating levers. The rotational speed of the output shaft can be infinitely varied by changing the throw of the oscillating levers.

Abstract: A continuously variable transmission is disclosed to change an input rotational velocity along a continuous spectrum using an eccentrically positioned cam cooperating with a counterweight assembly to counteract the imbalance generated by the eccentric cam. A plurality of cam followers in contact with the cam actuate crankshafts that drive planetary gears disposed about the crankshaft and cooperate with overrunning clutches. The overrunning clutch with the highest instantaneous velocity drives a sun gear connected to an output shaft. The velocity of the output shaft is governed by the eccentricity of the cam.

Abstract: An input shaft includes a cam configured to have a variable diameter profile. An oscillating arm tracks the cam profile. Oscillating motion of the arm is converted by roller clutches back to rotary motion. Speed variation is accomplished by moving the arms axially so that they contact the cam at points of varying cam diameter. The cam is configured to eliminate torque surges at all speed ratios, resulting in smooth delivery of torque under all conditions. An appropriate cam surface providing this result is disclosed.

Abstract: A mechanical transmission converts rotational motion of an input drive shaft to an alternating radially directed motion of a selected amplitude. The alternating motion imparts rotational movement to an output driven shaft through imposition of one-way clutches. The alternating radially directed motion is varied by means of a rotatable self-balancing cam assembly. The self-balancing cam assembly includes a working, radially offsettable cam component and a compensating counterbalance. The cam and counterbalance are interconnected by a plurality of eccentric orbital coupling elements which rotate with the input drive shaft and are selectively rotatable thereabout. These impart simultaneous radial movement to the cam and counterbalance as desired to maintain the transmission in a dynamically balanced condition over its full range of operation.

Abstract: A variable transmission having an input shaft, a lobed cam slidably splined on said shaft, and a plurality of pivotedly mounted cam followers which mechanically engage the cam is disclosed. The cam follwers are connected to an output shaft through intermediation of a one-way clutch mechanism. Each cam follower includes a steerable contact member whose orientation may be modified to induce a coaxially directioned, displacing force on the cam. The displacement of the cam effects a shifting of the transmission ratio.
