Wår blandebatterlet er tilkoplot, vil ventilkjeglen presses til iipen stilling ved hjelp av kontakts tykket 22, sota vad hjelp av ribber er Innsatt i utboringen 27, og motvirker cienaed f jværkraften 19. Sokkelen 10 skrues p& en forseglende oåte fast i et vanlig tilslutningsstykko 23. Un base 10, aoa is sealed down O-ring 11, or introduced into the concentric bore 1 bushing 1, and axially retained with the help of two or more balls 12. ?or & give a positive retention, the balls are ir.onter i don hollow axle pin 4 with the aid of diametrically unset hollows 13, and is pressed by the wall in the bore 26 to the rosette 6 into 1 cn annular recess 14, soia follows the radius of the balls. 2n conical valve 13, which is retained by the valve rod 17, is placed in the bore 15 of the base 10, and a ribbed structure is used to ensure concentric bearing 1 of the sleeve 16. If the mixing battery is disconnected, the valve cone will ice the gasket 21, is pressed by spring 19 against valve set 20, thus shutting off the water supply. When the mixing valve is connected, the valve cone will be pressed into the open position by means of the contact thickness 22, so that by means of ribs it is inserted into the bore 27, and counteracts the spring force 19. The base 10 is screwed onto a sealing nut into a standard connection piece 23.

Virko3s&tene for dette rørkoplingsutstyrot or eo:u følgers Under aksiell forskyvning laot fjurkraften IS, bringes den ringformede utsparing 25 til a ligge rett imot de radiclt arrangerte kuler 12, soa dermed fur adgang til a forlate den ringfamedc utsparing 14. På denne uiåten tillates cn aksiell frigjøring av forbindelsen. Dtter hvert sou fråkoplingen skrider froa, vil ventilkjeglen 10 danne kontakt iaed ventllsetct og derved stenge av vannstrøiiaen før 0-ring 11 mister forseglingaeffekten. Uår tilkopling påny skal gjennomføres, beveges rosetten aksielt til et punkt hvor kulen© 12 vil tillatte en riktig forbindelse. P&ny vil 0-ringen 11 nå sin forseglende stilling før ventllkjeglen 12 kommer klar av ventilsetet og derved gir gjennorns tr emning. The functions of this pipe coupling device are as follows: During axial displacement under the force of fire IS, the annular recess 25 is brought to lie directly against the radially arranged balls 12, thereby allowing access to leave the annular recess 14. In this way, axial release of the compound. As soon as the disconnection progresses, the valve cone 10 will make contact with the valve assembly and thereby shut off the water jet before the O-ring 11 loses its sealing effect. If reconnection is to be carried out, the rosette is moved axially to a point where the ball © 12 will allow a correct connection. Newly, the 0-ring 11 will reach its sealing position before the valve cone 12 comes clear of the valve seat, thereby providing normal discharge.

Så snart seia kulene 12 griper inn 1 den ringformede utsparing 14, blir rosetten presset til lesestilling av fjarkrafton. As soon as said balls 12 engage 1 the annular recess 14, the rosette is pressed into reading position by fjarkrafton.
