Textile machines that produce take-up packages

Abstract

A textile machine that produces take-up packages with control valves 1 , whereby the control valves 1 each have a valve body 2 , a piston 3 and a plunger 4 , whereby the plunger 4 comprises a front seal seat 5 and a rear seal seat 6 as well as seals 9 , with which outlets, such as a main line 14 , a pilot line 19 , a connection 16 and at least one vent 15 are alternately sealable in the valve body 2 , and the piston 3 has a piston seal 8 that separates two air circuits from each other. Contact surfaces 11 are designed in the valve body, at which the corresponding surfaces 12 of the front and rear seal seats 5, 6 of the plunger 4 can be brought into abutment.

What is claimed is: 
     
         1 . A textile machine that produces take-up packages with control valves ( 1 ), whereby the control valves ( 1 ) each have a valve body ( 2 ), a piston ( 3 ) and a plunger ( 4 ), whereby the plunger ( 4 ) comprises a front seal seat ( 5 ) and a rear seal seat ( 6 ) as well as seals ( 9 ), with which outlets, such as a main line ( 14 ), a pilot line ( 19 ), a connection ( 16 ) and at least one vent ( 15 ) are alternately sealable in the valve body ( 2 ), and the piston ( 3 ) has a piston seal ( 8 ) that separates two air circuits from each other,
 characterized in that   contact surfaces ( 11 ) are designed in the valve body ( 2 ), at which the corresponding surfaces ( 12 ) of the front and rear seal seats ( 5 ,  6 ) of the plunger ( 4 ) can be brought into abutment.   
     
     
         2 . The textile machine that produces take-up packages according to  claim 1 , characterized in that the surfaces ( 12 ) corresponding to the seals ( 9 ) have a conical design. 
     
     
         3 . The textile machine that produces take-up packages according to  claim 1 , characterized in that the piston ( 3 ) and the plunger ( 4 ) are designed in two pieces. 
     
     
         4 . The textile machine that produces take-up packages according to  claim 1 , characterized in that a supporting element ( 10 ) is available that is positioned so that the piston ( 3 ) is secured to the plunger ( 4 ) and the piston seal ( 8 ) can be affixed to the piston ( 3 ). 
     
     
         5 . The textile machine that produces take-up packages according to  claim 1 , characterized in that a connection designed as a bottleneck is integrated between the main line ( 14 ) and pilot line ( 19 ) in the plunger ( 4 ). 
     
     
         6 . The textile machine that produces take-up packages according to  claim 5 , characterized in that the bottleneck in the plunger ( 4 ) is designed with a separate fixed throttle ( 13 ). 
     
     
         7 . The textile machine that produces take-up packages according to  claim 1 , characterized in that the seals ( 9 ) are designed as O-rings. 
     
     
         8 . The textile machine that produces take-up packages according to  claim 1 , characterized in that the supporting element ( 10 ) can be attached to the plunger ( 4 ) without destruction and unattached. 
     
     
         9 . The textile machine that produces take-up packages according to  claim 1 , characterized in that the control valve ( 1 ) is designed as an individual or multiple unit.
