Both the coupling units each contain, inter alia, a shut-off valve 3 which is closed when the coupling i: second and thereby opens a free passage through the common coupling unit. When the coupling sleeve 1 and the nipple 2 when coupling the other. During the tortuous coupling movement, the valve cone 4 is retracted backwards in the resilient coupling part. When the coupling movement is completed in the coupling sleeve and the nipple, respectively, the desired free passage of the pressure medium is obtained, usually new hydraulic oil. If the coupling parts are pulled apart, opposite movement occurs and the respective valve cone 4 closes in the coupling sleeve and the coupling nipple, respectively. - If a hydraulic line is previously closed and subjected to an oil pressure, a non-insignificant overpressure on the valve cone 4 usually remains after disconnection, which to a great extent makes it difficult or impossible to renew the connection. Such overpressure can also occur when a tool loads its hydraulic cylinder and the oil therefrom affects the valve pin 4 in the connected quick coupling part.

- För att underlätta honkoppllngen och få låga hopkonplingskrafter, 'helst lägre än de ovan angivna, har man i vissa fall försett respek- tive kopplíngsdel med en separat avlasthingsventil SÅ Denna kan vara utförd på olika sätt t ex fjäderbelastad kula eller ventilkägla.

This can be designed in different ways, for example a spring-loaded ball or valve cone. In Fig. 5, such a known relief valve has been marked with a protruding ball bearing in the valve cone 4. The relief valve 5 in the passage must be small in order for the capping operator to be able to push up the valve 5 when it is pressurized. _ loaded; The oil which is relieved of the opening of the valve 5 is collected in the common drainage space of the coupling.

Neo hänsyn till ovanstáenoe uppstår betyaanae svarigheter att un- der kort kopplingsmoment kunna avlasta aktuell ledning. Dessa svåf rigneter har i praktiken ofta visat sig ha sådan storlek att en sammankoppling omäjliggöres utan att man skauemässigt valdför sig *pà kopplingen.In view of the above, there are significant responsibilities to be able to relieve the current line during a short connection moment. In practice, these floating features have often been shown to be of such a size that an interconnection is made impossible without arbitrary choice * on the connection.

V För att lösa ovanstående protlem har följanue uppfinning utvecklats :baae för att minska ooh avlasta mot_kopplingen verkande tryck samt för att samla_upp men överskottsolja som erhålles vid ett hopkopp- lingsmoment. _I figur 3 visas en avlastningsanoruning, tryckavlastare 6, för en till en tryckleuning kopplad nippel 2. För att avlasta uenna leuninš har till nippeln 2 anslutits en aaapter 7.

Motsvarande adapter färsen kotplingshylsa (1) kan utföras på møtsvarande sätt.In order to solve the above problem, the following invention has been developed: both for reducing and relieving the pressure acting on the coupling and for collecting excess oil obtained at a coupling moment. Figure 3 shows a relief connection, pressure reliever 6, for a nipple 2 connected to a pressure rail. To relieve a single rail, an adapter 7 is connected to the nipple 2. This is such a geometric shape that it connects to the nipple 2 in the same way as a corresponding coupling sleeve 1; The adapter can also be provided by temporarily looting a coupling sleeve (1), the female part, on its coupling part. The corresponding adapter mince sleeve sleeve (1) can be made in an appropriate manner.

Dräneringsspindeln 9 har en tvärsgående borrning 40 och en men den- na samverkande genomgående borrning 11. Borrningarna 10 och 11 har direkt förßindelse med varandra. Dräneringsspindeln 9 har i sin bak- re del försetts-med en slangnippel 12 till vilken är kopplad en drä- neringsledning 15~av förutbestämd längd. Dräneringsspindeln 9 har ett _ vred 14 som kan förses med radiellt riktade hål 15 i vilka man kan _* applicera en mejsel eller liknande föremål för att kunna manuellt 'underlätta'vridning av spindeln 9, A48 317 Funktion _-l 7Dâ en med nippel-försedd 1edníng_skal1 avlàstas anslutas till nip- V S _pe1n 2 ovan.beskrivna adapter 7.

The bores 10 and 11 have a direct connection with each other. The drainage spindle 9 has in its rear part been provided with a hose nipple 12 to which a drainage line 15 ~ of a predetermined length is connected. The drainage spindle 9 has a knob 14 which can be provided with radially directed holes 15 in which a chisel or similar object can be applied in order to be able to manually "facilitate" rotation of the spindle 9, A48 317 Function _-1 7Da one with nipple provided 1edníng_skal1 to be unloaded is connected to the nip- VS _pe1n 2 above.described adapter 7. The drainage pin 9 is threaded into the threads and rotated until the front end of the spinal hits the valve n 'jaw.4. By further turning the spindle 9, the valve cone 4 will be lifted from its seat, thereby creating a free channel> through the valve 5 and through the drainage spindle 9, the nipple 12 and the drain line 15 to a collecting vessel for the oil. After this operation, the adapter 7 is removed with the drain spindle 9, the nipple _ 12 and the drain line 1š.
