Patent ID: 6986501

Claim:
Pressure fluid control valve, for example a pneumatic valve or a hydraulic valve, comprising: a) a valve body having (1) a distribution channel ( 12 ) in form of a bore, having an inside diameter ( 23 ) and grooves extending radially outward from distribution channel ( 12 ), (2) and at least two further channels ( 8 ), the further channels leading to the distribution channel, b) at least one piston arranged in the distribution channel, the piston ( 11 ) having: (1) an intermediate element ( 26 ), (2) collars ( 20 ) facing away from each other and connected to the intermediate element ( 26 ), and (3) at least one sealing element ( 22 ), c) at least two electrically operated coils ( 174 ) for actuating piston by electromagnetic force onto at least one of the collars ( 20 ) and move them between at least two switching positions to open and close fluid communication between respective ones of further channels and the distribution channel, each coil arranged in the distribution channel within the grooves and adjacent to the opening ( 91 ) of the further channels, whereby an inside diameter ( 176 ) of the coils ( 174 ) corresponds with the inside diameter ( 23 ) of the distribution channel ( 12 ).
