Pilot adjuster-connector for adjusting the speed of pneumatic pressure

Starter connection for progressive pressurizing of pneumatic

Compressed air flow regulating devices

Rotary switching connectors providing both connection of the pipes with each other or to fixed members and for establishing the flow of fluid from the ones to the others or interrupting said flow by closing off the upstream circuits and venting the downstream circuits to the atmosphere. They are formed of two coupled elements 1 and 2 able to be manually rotated with respect to each other about an axis XX and to keep the position which is given them. An inlet channel 4 in element 2 and an outlet channel 3 in element 1 each equipped with an integrated connector 66 and 55 open into their respective adjacent faces over the same circle of radius XY. The angular registration of these orifices allows the sealed bidirectional passage of the fluid of the device by means of a seal 8 housed in a cup 7 at the periphery of channel 4 and compressed between the two elements 1 and 2. In any other rotary indexing position, channel 4 is closed by the sealing application of seal 8 to the smooth face II of element 1 and the outlet channel 3 which comprises no seal is in connection with the atmosphere through a bore 9. The rotary switching connector may comprise a plurality of inlets and outlets providing different passage combinations.

Pneumatic sensors for the control of pneumatic cycles

The invention relates to a compressed fluid saving device positioned between the outlet of a distributor and the admission of a pneumatic jack. The device comprises a valve which is kept open, to allow the flow of driving fluid into one chamber of the jack from the start and right through the stroke, by the exhaust back-pressure escaping from the other chamber of the jack, and acting on the piston of said valve. When the back-pressure disappears, the valve closes under the action of a screw-adjustable spring.
