Spring biased spool type valve controller for a pneumatic dual diaphragm control system

The invention relates to a direct acting pneumatic control system for controlling a dual diaphragm, or double acting cylinder type automatic guiding system. The control device and system is used to selectively adjust the position of one end of a roll relative to the opposite end, in order to adjust the position of an endless web traveling over a series of rolls. In order to adjust and control the guide roll position, it is necessary to alternately exhaust one diaphragm, and or cylinder end, while maintaining the flow of air to the opposite diaphragm or cylinder end. This in effect shifts the roll in a lateral position, effectively steering the web in the proper direction to effect the necessary web correction. To activate and control the valve position, the control valve is equipped with a palm which follows the web and continually monitors the web position and activates the control valve spool to modulate the "flow-exhaust" rates to bring the web to a corrected position with no over-run or "hunting" for position. The palm and its associated rod must follow the web when the web is moving away from the palm.

Fluid power device with rollers

Rotary actuator

A rotary actuator (100) having a reference structure (110), an output member (113) arranged for rotary movement relative to the reference structure, a first linear motor (116) arranged to selectively apply an output force urging a first motor member (119) and a second motor member (122) apart along a generally linear direction, in which the first linear motor is configured and arranged to cause a torque between the output member and the reference structure in a first direction, and second linear motor (137) arranged to selectively apply an output force urging a second linear motor first member (134) and a second motor member (137) apart along a generally linear direction, in which the second linear motor is configured and arranged to cause a torque between the output member and the reference structure in a direction opposite to the first direction.

Controlling rotation of butterfly valve by fraction of turn - utilises piston in cylinder moved in translation, under fluid pressure and in rotation

The rotating butterfly valve or tap is controlled by motor so that valve rotating mechanism turns by fractions of a turn. A piston (8) in hollow cylinder (1) is moved in tramlation by fluid under pressure and also rotates. Transmission assemblies (12, 13) transfer movement to a driven assembly (10) which rotates and is centred by bridging section (4). The cylinder is closed (27, 30) and radial orifices (2, 3) permit passage of a fluid under pressure. A shoulder on bridging section prevents rotating driven assembly from moving in tramlation. Its shaft (11) rotates the tap or valve blanking mechanism.

Electro-hydraulic rotary servo motor - converts linear piston movement to rotary movement in short space

The motor produces alternating rotary movements at high frequency and torque. The linear movement of the piston is converted to a rotary one in a very short space, typically by a mechanism in the form of a nut with planetary rollers, or recirculatory balls. Means can be provided to absorb the alternating axial efforts caused by the piston movement under the action of the hydraulic fluid, between two balancing chambers. Oil flow can be regulated by a signal from a position detector on the end of the shaft, thus regulating speed of piston displacement, typically by a servo valve.

Piston drive mechanism for axial and angular displacement of a machine element

Patent FR2133784B1

Controlled tilting mechanism for concrete slab former - has two rams coupled to separate crankpins on flat sided component

The drive mechanism tilts a machine part to and fro through an accurately defined angle, so that the two end positions are always the same. At right angles to the axis of rotation (11) is a link (1) flat one side, and on which there are two crankpins (3, 7) spaced apart at a predetermined angle about the axis. The drive is effected by the piston rods (4, 8) of two rams (5, 9) each pivoting about a fixed point (6, 10). The angle is pref. determined by the extended and retracted positions of the piston rods.

Quarter turn valve control device comprising a hydraulic actuator with variable volume piston

The device comprises a hydraulic actuator (5) comprising a central chamber separating the extreme ends (10) of two pistons (12). The pistons are symmetrical and are joined by a rack (13) and pinion (14). Rotation of the pinion reduces the volume of the piston and restricts the flow of liquid through the channel (16).
