Pneumatic connection for movable object, e.g. sleigh, comprises plunger with holes in its mantle connected to channels in plunger mantle located in object

摘要

#CMT# #/CMT# The connection (10) comprises a gas conduit (11) connected to the movable object (18), a plunger (14) connected to one end of the conduit, a plunger casing (17) located in the object and a guide (19) in working contact with the object. The plunger mantle has at least one hole (20) extending through it in communication with the conduit. The casing wall contains at least one channel (23) connected to the bore(s) in the plunger mantle. #CMT#USE : #/CMT# For providing a gas connection with a moving object, e.g. a pneumatically operated sleigh. #CMT#ADVANTAGE : #/CMT# Objects can be moved with far greater precision in the order of several nm without the need for hoses or pipes to be guided by robot arms. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The figure shows a cross-section of the pneumatic connection. 10 : Pneumatic connection 11 : Gas conduit 14 : Plunger 17 : Plunger casing 18 : Sleigh 19 : Guide 20 : Hole in plunger mantle 23 : Groove in plunger casing wall.
