Device with rotatable pipe connection and hose end connection

The invention relates to a rotatable ear connector, and more particularly to drill connectors. Sur application in hose couplings Such a rotatable connection should prevent the hose from twisting, that the assembly is particularly easy and on the other hand Tfatiwi mä & a. wixi-z that the sneeze. a resistance against rotation in the opposite direction if it is exposed to pressure. no pressure material should also be used.

the device leaks out, even if it is "I am" rather high, internal "work pressure"! for example ia range τοη 4-βΟΟ pounds 3e Qaadratzoii (515 kg / c * ^S ).

Devices for pipe connection of this type generally consist of two pipe-like bodies which are connected to one another in such a way that they can easily rotate relative to one another, in the case of a hose end connection one part generally for the purpose of fastening to the part, xu dee the hose is part of it, is screwed on, while the other part engages at the end of the hose and there

attached in any conventional manner resulting in this suitable to withstand the high internal pressure at which the

Such gate directions may lie in a line course, "I constricting rotatable connection" a rotary joint for 9O ^e or a rotary joint for two times include 90 °.

One of the most important requirements for such devices with pipe connectors or hose connectors is that the internal compressive load, which, as stated, can be about 4500 pounds per square inch (515 ig / cm ² ), does not cause any axial relative movement between the parts, which for example could interfere with the free rotating movement.

The invention is therefore based on the object a Device with drill connector or hose end connection closed create * the see, especially for hoses for high internal pressure "* i £ B.et and iron free" rotary movement xwisehen des. ropes

enables, while on the other hand no axial movement or practically no axial movement swieehea dta individual parts It will be allowed, the vorricntüög itself but estspreeheäd against Pressure loss is sealed even with high pressure loads « The new device according to the invention is essentially characterized by the following items: A circular cylindrical female part, a tubular male part enclosed in the female part, a circular ring «Wipe the feminine and the masculine part of it »Sits between the two parts, with both the male and the female part at a separation in axial sighting is prevented, but both parts rotate freely into one another »^ Suitable sealing rings are in sealing ring

■ with the female and the male part to avoid pressure medium losses with internal overpressure % u TärMidars, the sssslicke part has a bore running in the transverse direction, which the large bore of the male part with a pressure ruff for the inflow of the pressure medium under overpressure This pressure also acts on the male part, which is located in the female part, in order to create a completely balanced or practically balanced internal pressure that does not allow any axially directed relative movement between the female and the male part ₅ which could interfere with their free rotation.

At. a preferred etching form of the device according to the invention get two coaxially arranged circle =

Föraige rings for use _s which overlap with their inner ends, each circular ring ait its inner limiting surface rests on corresponding sighting rings at the rear end, which in turn press on a shoulder of the associated circular ring.

In the part of the description that now follows, the device is intended according to the invention under B # sugnshas on the drawing are explained in more detail.

In the drawing is:

Fig. 1 is a side view, partially in section, one Hose end connection with a rotatable connection according to the invention;

Fig. 2 is an end view of the device of Fig. 2 and the ^ Fig. 3t 4- and 5 each a side view «partially in Section of three different embodiments of the device according to the invention

The hose end connection according to FIGS. 1 and 2 has a cylindrical female part 1 which has hexagonal surfaces 2 on the outside and a thread at its outer end 5 carries what Si ^ making the connection with a component to which the hose belongs.

The female part 1 has three different inner diameters of the coaxial bores 4, 5 and 6. The male Part 7, which is enclosed by the female rope, has four cylindrical sections 7, 8, 9 arranged coaxially

«Ad 10 with different diameters, * u which the Intermediate shoulders 11, 12 tuid 15 belong, of which the shoulder 12 has the form of a purely krelsringfSrmigen flange »

The male rope? can be completely free inside of the female part and has a protruding part that engages the end of the viewing tube 14 during the Seltlaueh himself a * oif this protruding part is held in place by hexagonal fastening elements 15

Inside the female part 1 sits a ring 17, who is thereby held in his position “that the outer end 18 of the female part against an inclined surface is crimped at the end of this ring · This ring is worn on the outside a hat in which there is a sealing ring * ^. The ring 17 has there is also an inner axial bore with two different diameters, of which the smaller diameter is the part 10 of the male part tightly fitting HMachllesst. The section with the larger inner diameter of the ring contains a sealing ring 20 and a behind it. Ring 21 made of thermoplastic * material that rests on a shoulder that is where the two coaxial holes in the ring to each otheratobbög.

The male part wears an auosordora at the back "I lying ring 23 made of thermoplastic material, which is attached to the I.

Shoulder 12 rests, a sealing ring 22 and a second inner ring 23a made of thermoplastic®]! Material that at the end of the ring 17, oo that in this way the

male part is held in its position in the female part "

The male part 7 has a tubular extension 24 · » which engages in the Bohxung 4 in the female part} this The extension has individual slots 25 »in which a screwdriver or other tool can reach out if the male part is inserted into the end "of the hose" the Extension carries a sealing ring 26 and an underlying ring 27 of thermoplastic material that adheres to it the shoulder 11 puts on

In the wall of the little part there is one

transverse bore 28, so that the upper pressure of the pressure

by means of the sealing ring 20 and the one behind it Hing 23 can act; For this purpose, the inside diameter of the part of the hinge which the transversely running bore allows surrounds, larger than the aera of the male part, so that in this way a bridge space for the attack of the pressure * means wins «In order to bring about a practically balanced internal pressure, the pressure medium can be applied to the outer element of the Part 24 of the male part act, dlo Quorschnltfcsberelohe that part · on which the pressure of the pressure medium acts are calculated in such a way that in the end there is no load can work because such an axial displacement of the male and female parts »», hold on to me and a free rotation at high pressures would change

In the female part there is a crosswise ** Fende hole 29, which has the task of trapped the outlet To allow air between the sifting rings 22 and 26 during the assembly of the gate direction and also a complete. Compensation of the areas between the sealing rings 22 and 26 on the one hand and 20 on the other hand, taking into account the atmospheric pressure.

In the second embodiment of the device according to the invention, which is shown in FIG. 3, the cylindrical female part i has flat hexagonal surfaces 2 and has a. Internal thread 5, which is used to establish the connection with a »pipe or another component. Here, too, the female part Ϊ three coaxial bores 4 _y 5 and 6 with different diameters * which is located in the female part, the male part 7 "has similarly as in the first execution" for a portion of reduced diameter »of the bore 4 protrudes into the female part, and bears «4» g- £ §n & g? Sealing rings 26 and 27, of which the ring 26 is preferably in the form of a sealing ring with the one shown. Has cross-section, while the Hins 27 is oin the back or ring is made of thermoplastic material, which rests on a shoulder 11 on the male part, and both Hisg «di® Eisg £ l» «he«
