Referring to Fig. 1, the distribution device 20 comprises a conventional, electrically powered, portable one Air compressor 24 acting as a source of driving fluid under pressure, and a closed container 26, which serves as a source for the fluid to be dispensed Material serves. For the purpose of explaining this

BS / 0226

For example, it can be assumed that the flowable material is suitably diluted paint. Though as Air pressure source of portable compressor 24 is shown, it will be understood that other pressure sources are used can be. The distribution device 20 also includes a conventional suction spray head 28 which acts as a distribution device serves to distribute the paint, a first line 30 for conducting the paint from the closed Container 26 to the spray head 28, a second line 32, which is connected to the air compressor 24, to under To supply pressurized air to the container 26 to cause the paint from the closed container 26 to be fed to the spray head 28, and a control device 22 to control the flow of paint from the closed container 26 to the spray head 28. By the line 32 and through a further line 44 operatively connected to it, the compressor 24 can run continuously Supply flowing air under pressure to the suction spray head 28 with a continuous flow and also the closed one Supply container 26 with pressurized air to remove the paint from the closed container 26 to the To promote spray head 28.

As shown, the closed container 26 consists of a conventional paint can 34 with the lid removed is and in the upright position between a bottom plate 36 and a cover plate 38 by means of a plurality is clamped by elongated upright screws 40 in a conventional manner. To achieve an airtight seal, is a corresponding annular seal (not shown) between the top of the paint can 34 and 34 the cover plate 38 is used.

There are three threaded holes (not numbered) in the cover plate 38 provided. In the first of these threaded holes is the vertical leg of a three-way I-connector 42 screwed in, the two arms of which are connected to the ends of the line 32 and the additional line 44, respectively are. The other end of the line 44 is connected to the suction section of the spray head 28, to allow the conduit 32 to continuously flow air under pressure from the spray head 28 through the Three-way connector 42 and line 44 supplies, and also supplies the closed container 26 with air under pressure.

In the second threaded hole is a standard rope tube 46 screwed into a suitable external connector 48 for connection to the line 30. In the third threaded hole a combined drain and relief control device 50 (see also Pig. 7) is screwed in, the automatically ensures that the closed container and the lines in the event of excessive air pressure be relieved.

The continuous flow suction spray head 28 is threadedly connected to a port 52 of the conduit 44 and has a connection 54 for flowable material to which the line 30 through the control device 22 is connected is. The construction and operation of the spray head 28 are conventional and out of range of this invention.

In Fig. 2 the distribution device 20 is in connection shown with a pressure-fed paint roller 56 as a llaterialverteilungsgerät. The one to roll In contrast to paint that is sprayed, paint does not need to be diluted. The line 30 continues used to direct the paint from the closed container 26 to the controller 22, and the line is connected to the air compressor 24 to be pressurized to supply standing air to the container and thereby to cause the paint from the closed container 26 to be fed to the roller 56. The one shown in FIG Line 44 is not used, and therefore one arm of the three-way tee fitting 42 is through one usual threaded cap 58 closed.

The roller 56 loaded with pressure consists of a roller 59 with the usual core construction, which is pierced by a series of openings and covered with fabric can. The roller is supported for rotation by a correspondingly shaped tubular support 62, on one of which The end of the line 30 is connected via the control unit 22 for supplying paint. The tubular carrier 62 is provided with a number of suitable openings, the number in the direction towards the free end of the carrier 62 increases and through which the paint or other flowable material from inside the perforated Roller 59 can be fed. A screw 57 that holds the roller 59 on the tubular support 62, also closes and seals the end of the tubular support to prevent paint leakage. In Fig. 2, the tubular roll support 62 is partial

909885/0225

shown pulled out of the perforated roller 59 to show some of the openings 64.

The combined drain and relief control device 50, which is shown in Fig. 7 serves to prevent the closed container 26 from building up during excessive air pressure to relieve the pressure of spraying or rolling. It consists of a substantially tubular body 66 which is used for

ψ Convenient assembly comprises a substantially tubular upper section 67 with a screwed-on sleeve 68 and a substantially tubular lower section 70 which can be screwed into the cover plate 38 in FIGS. An annular valve seat 72 is inside the body 66 and is annular. Shoulder 74 formed in the sleeve 68. A spherical valve element 76, which fits loosely into the substantially tubular body 66 above the valve seat 72 to allow the passage of fluid around it, is pressed onto the valve seat 72 by a correspondingly strong coil spring 78 which rests against the shoulder 74. An adjustment of the spring force is possible through the threaded connection between the sleeve 68 and the upper section 67 of the body 66 . When the fluid pressure under the spherical valve element 76 exceeds the load applied by the spring 78, the spherical valve element 76 is raised to allow fluid to pass around it.

The controller 50 is also provided with a small air vent or groove 80 formed in the annular shoulder

is incised. The groove 80 is too narrow to the normal pressure build-up under the spherical valve element 76 during operation of the air compressor 24 (Pig. 1 and 2), but serves to relieve the rest of the pressure under the spherical valve 76, when the air compressor has been running and stopped. Therefore, especially when the distribution device exists 20 is used with the roller 56 (Fig. 2), no risk of residual pressure on the piston or the Air compressor 24 diaphragm which could overload the compressor motor or cause other damage. This enables the use of an air compressor driven by a motor with low starting torque will.

Mainly from Fig. 3 to 6, in which the control unit 22 is shown in detail, it will be apparent that the controller 22 includes a body 106 which preferably as a handle 108 with a head section 110 is designed. The body 106 may be made of nylon or the like.

The H _a ndgriff 108 has a smooth, substantially cylindrical and slightly tapered outer surface 112 which is designed so that it can be gripped by the user with one hand safely, and an elongate channel 114 therein, which includes a narrowed Absohnitt 115 . An open end portion 116 of channel 114 is threaded to receive a suitable connector 118 (FIG. 1 or FIG. 2) for conduit 30. From Figures 1 and 2 it will be understood that the connector

909885/0225 _-10 _

- ίο -

118 has a tubular insert portion (not shown) which in a conventional manner into the adjacent End of line 30 is inserted and secured in position by a conventional clamp wire 122 while the opposite end of lead 30 has a similar connector 126 and clamp wire 128 to the Has connection to the previously described terminal 48.

¥ / ie it is shown in Figs. 3 to 6 is in the other At the end of the channel 114 attached to the head portion 110 a substantially tubular insert 132, wherein an innermost end is designed in a hexagonal shape. The insert 132 is coaxial with the channel 114 and is provided with an internal thread to either the connection 54 of the spray head 28 (Fig. 1), which in a corresponding manner threaded, or to receive the roller support 62 of the roller 56 (Fig. 2) in a suitable manner is threaded at its end portion 134. While the body 106 can be made of nylon, the insert 132 should be made of brass od. The like. To be a firm connection for the spray head 28 or to create the role 56.

A cylindrical journal bearing 144 'that the narrowed section 115 of channel 114 crosses is in the head portion 110 of the body 106 is formed. As shown, the journal 144 extends completely through the head portion 110 transversely to the central narrowed portion 115 of the channel 114, so that the upper End of the journal bearing 144 approximately near the top

909885/0225 -11-

of the handle 108 opens. Corresponding coaxial countersinks 146 and 148 are on the opposite ends of the journal bearing 144 is formed.

A substantially cylindrical piston 150, which has a shaft portion 152 and a radially directed knurled head portion 154 is arranged in the journal bearing 144 and is axially movable and rotatable therein. Of the Piston 150 has a transverse bore 156 through its shaft portion 152. The piston 150 has a first Position (Pig. 3), in which the piston blocks the channel section 115 in order to close the control unit 22, regardless of a rotation of the piston 150, since the transverse bore 156 of the piston lies above the channel section 115. Loading elements in the form of a Coil spring 162 that wraps around shaft portion 152 of the Piston 150 between its head portion 154 and the Countersink 146 is arranged, serve to push the piston into its first position.

The piston I50 has a second axial position (a depressed Position according to Pig. 4) ι in which it can be rotated to the transverse bore 156 to a variable extent to bring with the channel section 115 in communication to to change the degree of opening of the control device 22 accordingly. The channel section 115 is sufficiently narrow in relation to the channel 114 to the stem portion 152 of the piston 150 in its second axial position To allow the channel 114 to be blocked completely, when the piston is rotated so that the transverse bore 156 is substantially transverse to the channel section

909885/0225 _ ₁₂ -

runs as shown in FIG. About the · effects The head portion 154 of the piston and a are to aid in rotational adjustment of the piston adjacent area of the outer surface 112 of the body 106 is marked accordingly, as for example in Pig. 2 is indicated. . .

Axial movement of the piston 150 in an upward direction depending on the action of the spring 162 is limited when the piston 150 reaches its first position, and by means of a snap ring 158 which is inserted into a corresponding circumferential groove 160 on the sticking section 152 of the piston 150 snaps into place. The snap ring forms a flange which rests against the body 106 in the counterbore 148. One axial movement of the piston 150 in the opposite direction (downward in FIGS. 3 and 4) when the piston 150 reached its second position, limited by the head portion 154, which extends radially over the countersink 146 extends beyond.

To seal the journal bearing 144, two are deformable O-rings 164 in axially spaced apart Circumferential grooves 166 used on the shaft portion 152 of the piston I50 on axially opposite sides of the Cross hole ■ 156 are formed.

The control unit 22 also has a releasable lock smeohanismus 168 to the piston 150 in its to releasably lock the depressed axial position while still rotating the piston I50 in this position is made possible. The locking mechanism 168

9098 85/0225

is located under the body 106 at its head end and consists of a slide 170 with a relatively long elongated hole 172 therein and an upwardly curved one Pinger flap 174. The slider 170 is on the body 106 via a relatively short elongated neck slidably arranged on the head portion 110 of the body 106 is formed and extends through the elongated hole 172 and somewhat beyond this and is secured by means of a round head machine socket 178, which is suitably secured in a threaded socket 180 in the boss 176. The approach 176 is arranged to allow one end 182 of slide 170 to be engaged and disengaged from the Shank section 152 of the piston 150 in its second (depressed) axial position can slide, and this End 182 has a concave recessed portion 184 which has a curvature such that it fits onto the shaft portion 152 fits. The end 182 of the slide 170 is arranged so that it is dea with the shaft portion 152 Piston 150 ° in its depressed position immediately come into engagement above the snap ring 158, as shown in FIG. Since the each 162 the piston 150 so loaded that the snap ring 158 is caused to be at the bottom of the end 182 of the slide to lie, the locking amohaniamua 168 is effective to lock the piston 150 in its second axial position, so that the user does not have to constantly depress the plunger with his thumb or hand. Because the concave cut portion 184 of the end 182 of the slide 170 of the curvature of the shaft section 152 of the piston 150 corresponds, the interlocking

909885/0225 -u_

lungsmeohanismus 168 rotates the piston 150 in its depressed position while holding the piston 150 releasably locked therein. The slide 170 can by means of of the finger flap 174 to unlock the plunger 150, thereby releasing the plunger 150 To give the possibility of being moved axially into its first axial position by the spring 162, as shown in FIG. 3 is shown.

From Pig. 2 it will be understood that in the case where the controller 22 is with the roll loaded with pressure 56, assuming the air compressor 24 has started, the piston 150 will normally be used releasable in its second (depressed) position by means of of the locking mechanism 168 should be locked and also rotatably adjusted so that the Controller 22 is fully open until the paint fills and saturates roller 56, whereupon the piston can be adjusted by rotation so that the amount of ink is reduced to the saturation of the roller 56, upright and thereby enables precise rolling. The electricity can be stopped by either Unlocking the piston 150 and by allowing the piston 150 axially through the spring 162 in its first axial position is moved, or by rotating the piston accordingly in a shut-off position in the depressed Condition of the piston.

From Fig. 1 it will be understood that in the event that the controller 22 is used with the spray head 28, assuming the air compressor 24 started
