Abstract (en)
[origin: WO9002883A1] The invention relates to a controlled connector-regulator allowing the occurrence of two different speeds in the same stroke of a double acting pneumatic cylinder. In the absence of control signal at the orifice (13) of the apparatus, the exhaust pressure coming from the cylinder (30) effecting its rod output stroke finds the return valve (14) closed and maintains the piston (2) against the stop (9) of which the adjustment determines a first flow rate between the needle (15) at the extremity of the piston and its seat (16), which flow rate corresponds to the high speed. The occurrence of a pressure signal in the chamber (6) displaces the piston (2) till it butts against a second screw (7) of which the regulation allows a second flow rate smaller than the first one and which thus determines the second speed. The return valve (14) opens to the inlet flow traversing backwards the apparatus in the direction of the cylinder in its reverse stroke, and the control signal having disappeared, this pressure pushes back the piston (2) to the high speed position. Applications to pneumatic techniques.
