Description

SPray pun for applying liquid This invention relates to a spray gun for applying liquid. The spray gun is of the kind comprising a gun body, a connection point for connection to a source of compressed air or other gas, a nozzle holder at the front end of the gun, a nozzle body formed with a through-hole provided in said nozzle holder, a nozzle needle movable axially in said hole between a forward or initial position in which it seals the through-hole against the emergence of liquid and a rearward or release position in which it permits the emergence of liquid from the front orifice of the through-hole, a paint container connected to the rear region of the through-hole, and a passageway for leading compressed air or other gas from said connection point to said nozzle.Such a spray gun will hereinafter be referred to as "a spray gun of the kind set forth".
Such spray guns of the kind set forth are known, for instance, for applying paints, and as a rule the paint container is connected rigidly to the gun body in such guns.
One problem with the known spray guns of the kind set forth is that each time a change is made from one paint to another the paint container and the entire inner region of the gun body which comes into contact with the paint have to be carefully cleaned, which is extremely costly and is also often not possible to its full extent, so that when a new paint is being sprayed a check must first of all be made to see whether remnants of the previously sprayed paint are still being applied during spraying.
It is an object of the present invention to improve a spray gun so that the cleaning process before a change of paint is considerably simplified.
According to the present invention there is provided a spray gun of the kind set forth for applying liquid, wherein the the nozzle holder, the nozzle body and the paint container together form one structural unit, and wherein the structural unit is removably attached to the front end of the gun body.
In the present spray, the structural unit which is formed by the nozzle holder, nozzle body and paint container can therefore be removed as a whole, so that practically all the parts which come into contact with paint are removed from the gun body and are exchanged for another structural unit with a nozzle holder, nozzle body and paint container or can be carefully cleaned.
The only component which remains in the gun body and which also comes into contact with paint is the nozzle needle, which however can be cleaned simply after removal of the structural unit, as its section which otherwise extends into the structural unit and comes into contact with paint protrudes across the front end of the gun body after the removal of the structural unit.
The paint container may be connected to a tubular element through which the nozzle needle extends in the assembled state and to the front end of which the nozzle holder is attached. The paint container and tubular element can be constructed as effectively integral with one another.
In order to ensure that no compressed air escapes into the transition area between the gun body and the structural unit, the tubular element may have in its rear end region at least one annular groove which is formed on its outside, into which groove is inserted an O-ring.
Compressed air may be supplied from the gun body to the space between the nozzle body and the nozzle holder by a compressed air duct which extends through the tubular element parallel to the orifice for the nozzle needle.
In order to obtain a secure and reliable connection between the nozzle holder and tubular element, the nozzle holder may be screwed to the tubular element.
In order that in operation no paint can pass from the paint container backwards into the tubular element and possibly from there even into the gun body, a sealing element which in the assembled state surrounds the nozzle needle may be provided in the tubular element behind the connection to the paint container.
One problem with spray guns of the kind set forth is that for cleaning the entire gun body is placed in a cleaning fluid and is rinsed through, whereby even the non-return valve in the connection point for connection to the compressed air source is also rinsed. In the process there is the danger that dissolved contaminants will be deposited in the region of the non-return valve and will impair the operation thereof.
In order to avoid such an accumulation of dirt, in the case of a spray gun which has a non-return valve which is opened by being acted on by an activating element in the connection point for connection to the compressed air source, a tubular section containing the non-return valve may be removably attached, for instance screwed, to the gun body, so that the non-return valve can be removed from the gun body-together with said section before the previously mentioned cleaning operation is carried out.
In order to obtain a spray pattern which is as undisturbed as possible during operation in a spray gun of the kind set forth, and which is also kept unchanged after quite long operating periods, the front end of the nozzle needle may be located within the through-hole in the release position, the front end preferably being located at a distance from the front end of the throughhole in the release position..
Surprisingly, it has been demonstrated that this very simple measure clearly improves and stabilises the spray pattern. This seems to be due to the fact that, in operation, particles of paint are deposited on the front end of a nozzle needle which protrudes beyond the front end of the through-hole of the nozzle body both in the initial position and in the release position. In such spray guns, particles of the paint mist which is to be applied are dragged along out of the through-hole and hit these particles. Thus these paint mist particles are flung out of their normal path of movement which is determined by the actual spray pattern, which leads to disruption of the spray pattern.
These problems are avoided by the configuration in the present spray gun, obviously due to the fact that due to the position of the nozzle needle within the throughhole during spraying, there is no longer the risk of particles of paint being deposited on the outer surface of the nozzle needle.
In order to protect the nozzle needle of the present spray gun against breaking off, the front end of the nozzle needle may be located in the plane of the front orifice of the through-hole in the initial position, so that there is therefore no longer any part of the nozzle needle projecting beyond the front end of the nozzle body in the initial position as well.
In the present spray gun it is also possible to change the spray pattern in a simple manner by using interchangeable nozzle bodies while keeping the same nozzle needle. For this purpose, for instance in the case of a nozzle body with a relatively large crosssection of the exit area of the through-hole in the region of the front orifice, the nozzle needle in the initial position may be in sealing contact with a sealing section of the through-hole which is at a distance from the front end of the through-hole, so that the seal is produced by a region of the nozzle needle having a larger cross-section.
On the other hand, in the case of a nozzle body with a through-hole having a relatively small cross-section, in the region of the front orifice of the through-hole the nozzle needle in the initial position may be in sealing contact with a sealing section of the through-hole which extends from the front orifice of the through-hole via a partial region of its axial length, so that the seal is produced with a section of the nozzle needle having a relatively small cross-section and in the front region of the through-hole.
In order to enable the invention to be more readily understood, reference will now be made to the accompanying drawings, which illustrate diagrammatically and by way of example some embodiments thereof, and in which: Figure 1 is a section through part of a spray gun.
Figure 2 is a section of the front part of the spray gun in Figure 1 but showing a modified nozzle needle, Figure 3 is a section on a larger scale of that region of the spray gun which is encircled in Figure 2 with the nozzle needle in an initial position.
Figure 4 is a view similar to Figure 3 but showing the nozzle needle withdrawn into a release position, Figure 5 is a view similar to Figure 3 but showing a different nozzle body and, Figure 6 is a view similar to Figure 5 but showing the nozzle needle withdrawn into the release position.
Referring now to Figure 1 of the drawings, there is shown a spray gun which may for instance be used as a so-called airbrush. The spray gun has a gun body 11, in which a nozzle needle 63 which can be moved back and forth is held in a conventional manner, the needle being attached by its rear end to a receptacle (not shown), the forward movement of which is restricted by a transverse pin 56. An activating element 44 is held in the gun housing 11 so as to be pivotable about a pin 65, and the activating element 44 may be swivelled about the pin 65 with the aid of a handle 41, the degree of swivel being determined by a set screw 45 which is screwed into the handle 41 and is in contact with the activating element 44.The end of the activating element 44 which is remote from the pin 65 is engaged with one end 16 of an activating pin 15, which extends through a seal 13 and a bushing 14 screwed into a threaded bore in the gun body 11 and which engages with its other end a valve body 25. The valve body 25 is housed in a tube section 21 which is screwed into the gun body 11, and may be moved in the tube section 21 against the force of a spring 26 by displacing the activating pin 15, so that an O-ring 24 provided on the valve body 25 is lifted from the valve seat formed.
A connecting sleeve 27 is screwed into the outer end of the tube section 21, with the interposition of a sealing ring 28, the spring 26 being supported on the sleeve which serves to attach a hose which is connected to a source of compressed air.
A tubular element 34 is removably inserted into the front end of the gun body 11, coaxially with the nozzle needle 63, which element has on its outside O-rings 36 and 37, which are in sealing contact with inner surfaces on the gun body 11. The tubular element 34 may be clamped in the gun body 11, and the connection may be ensured by an attachment screw (not shown) extending transversely through the gun body 11.
A paint container 39 is formed on the tubular element 34, and the interior of which container is connected to the region of the tubular element 34 surrounding the nozzle needle 63.
On the front end of the tubular element 34 there is screwed a nozzle holder 32, which presses a nozzle body 33, with an O-ring 35 provided thereon, into sealing contact with the front end of the central orifice of the tubular element 34. The nozzle needle 63 extends into the through-hole of the nozzle body 33 in the usual manner, i.e. the nozzle needle 63 seals the through-hole of the nozzle body 33 in its forward or initial position.
Since the nozzle needle 63 of the spray gun in Figure 1 projects beyond the front end of the nozzle holder 32 at least in its sealing position as shown, there are projecting protective pins 31 in the nozzle holder 32 which protect the nozzle needle 63 from damage to its front end.
An air duct 12 extends through the gun body 11 from the valve seat for the O-ring 24 of the nozzle body 25 to an air duct 40, which runs through the tubular element 34 parallel to the nozzle needle 63 in the position shown. The front end of the air duct 40 is connected to an air duct which extends between the nozzle holder 32 and nozzle body 33 which becomes an annular space surrounding the front end of the nozzle body 33. Air which has passed through the duct 40 can emerge from the front end of the nozzle holder 32 and thus can entrain paint out of the through-hole in the nozzle body 33 and spray it in a conventional manner.
If the paint container 39 is filled with paint, the paint is located at the rear end of the through-hole of the nozzle body 33, as can be seen in Figure 1, but cannot enter the through-hole due to the sealing position of the nozzle needle 63. The backwards passage of paint in the region of the nozzle needle 63 is prevented by a seal 38 which is provided in the tubular element 34 and surrounds the nozzle needle 63. In this position, moreover, the compressed air in the interior of the tube body 21 effects a sealing position of the valve body 25 in which the during 24 is in sealing contact with the appropriate valve seat.
If the handle 41 is swivelled about the pin 65 by the user, the activating pin 15 is displaced towards the tube section 21, so that the valve body 25 is displaced against the pressure of the spring 26 and compressed air enters the duct 12 in the gun body 11 and from there flows through the compressed air duct 40 in the tubular element 34 to the annular space between the front end of the nozzle body 33 and nozzle holder 32 and emerges. At the same time, the displacement of the handle 41 displaces the nozzle needle 63 backwards (to the right in Figure 1) so that the through-hole is freed for the passage of paint from the paint container 39. The paint is then sprayed in a known manner by the action of the emerging compressed air.
If another paint is to be sprayed with the spray gun shown, the user only needs to remove the tubular element 34, with the nozzle holder 32 and nozzle body 33 attached thereto, from the front end of the gun body 11, the seal 38 sliding along the nozzle needle 63, which remains in the gun body 11, scraping off most of the paint which is adhering to the needle. If the tubular element 34 is removed, the nozzle needle 63 protrudes freely out of the gun body 11 and can easily be cleaned by wiping.
Since no parts of the gun body 11 have come into contact with the previously sprayed paint, there needs to be no additional cleaning. Rather, the user can simply attach a new structural unit consisting of tubular element 34, paint container 39, nozzle holder 32 and nozzle body 33 to the front end of the gun body 11 in order to spray another paint without the danger of remnants of paint from the previous spraying operation being sprayed as well.
Incidentally, if a thorough cleaning of the gun body 11, possibly together with the above-described structural unit, has to take place, the tube section 21 can be unscrewed from the gun body 11. If the outer end of the tube section 21 is still connected to the compressed air source, said connection does not need to be broken because the compressed air presses the nozzle body 25 into its sealing position, so that there is also no danger that when the tube section 21 is released from the gun body 11 compressed air will escape therefrom.
Referring now to Figures 2 to 4 of the drawings, the front part of the spray gun shown in these figures largely corresponds to that shown in Figure 1, and the same reference numbers are used for the same parts.
As can be seen in particular from Figures 3 and 4, the through-hole 133 of the nozzle body 33 is formed in the shape of a truncated cone over a section 133' (Figure 4) which lies at a distance from the front end of the nozzle body 33 and tapers from back to front. Near the front, a region which widens forwards to the orifice of the through-hole 133 is connected to the section 133'.
Due to this configuration, a tapering section 63' of the nozzle needle 63 in the initial position shown in Figure 3 is in sealing contact with the section 133' of the through-hole 133, while the region of the section 63' of the nozzle needle 63 which projects beyond section 133' protrudes into the region of the throughhole 133 which widens forwards, so that in this embodiment the front end of the section 63' is in the plane of the front end of the nozzle body 33 in the initial position of the nozzle needle 63.
If the nozzle needle 63 is withdrawn into its release position (Figure 4), there results an open annular space between its front section 63' and the section 133', which is in the shape of a truncated cone, of the through-hole 133 of the nozzle body 33, through which space paint can penetrate and is sprayed in a manner which is substantially due to the dimensions of the front, widening region of the through-hole 133 and the shape of the compressed air guidance system in the region of the outlet opening 40'. In this release position, the front end of the section 63' of the nozzle needle 63 is at a distance from the plane of the front end of the nozzle body 33 and hence from the plane of the outlet opening of the through-hole 133 and inside said through-hole, as Figure 4 shows.The nozzle needle 63' therefore does not affect the emergence and the guidance of the paint in the region of the outlet opening of the through-hole 133 and hence also does not affect the resulting spray pattern.
In the embodiment shown in Figures 5 and 6, instead of the nozzle body 33 there is a nozzle body 33', while the nozzle needle 63 and the nozzle holder 32 remain unchanged from Figures 3 and 4.
The nozzle body 33' differs from the nozzle body 33 in Figures 3 and 4 by the shape of its through-hole 233, which is in the form of a continuous truncated cone in the front region, so that the tapering section 63' of the nozzle needle 63 in the initial position in Figure 5 is in sealing contact with the through-hole 233 along the entire length of said region thereof which is in the shape of a truncated cone, and thereby does not protrude beyond the front end of the nozzle body 33'.
If the nozzle needle 63 is withdrawn into its release position (Figure 6), there results a free annular space about its front section 63' through which paint can emerge through the through-hole 233, and furthermore the front end of the section 63' is located within the through-hole 233 and at a distance from the front end thereof, as Figure 6 shows.
It can easily be recognised that, with the configuration of the through-hole 233, a spray pattern with a smaller diameter than with a nozzle body 33 having a throughhole 133 according to Figures 3 and 4 results
