摘要

#CMT# #/CMT# The switching valve comprises a capsule-shaped closing element (60) at a guide pin (28). A valve-piece (32) is centered at a center seat (74). The valve-piece has a seat face (62) above the center seat. The seat face of the center seat has spherical surfaces, which has an identical ball center point (66). A blind hole (82) is provided in an head area of the guide pin, which is connected hydraulically with a cross hole (84). #CMT#USE : #/CMT# Switching valve for injectors, particularly fuel injectors. #CMT#ADVANTAGE : #/CMT# The switching valve comprises a capsule-shaped closing element at a guide pin, and hence ensures a simple and economical switching valve with a safe operation. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a schematic view of a switching valve of a fuel injector. 28 : Guide pin 32 : Valve-piece 60 : Closing element 62 : Seat face 66 : Ball center point 74 : Center seat 82 : Blind hole 84 : Cross hole.
