Abstract

Paint spray gun with pneumatic paint atomisation, a valve cone which is designed as air shut-off valve and can be operated by means of a trigger and also a regulation cock for adjusting the air throughput being arranged coaxially in a housing bore.

Description

Die Erfindung bezieht sich auf eine FarbspritzpistoleThe invention relates to a paint spray gun

mit pneumatischer Farbzerstäubung, deren Luftkanal durch einen unter Federspannung stehenden Ventilkegel verschließbar ist, der mit einem von Hand betätigbaren Abzugsbügel öffenbar ist.with pneumatic paint atomization, the air channel of which is through an under Spring-tensioned valve cone can be closed, which can be operated by hand Trigger guard is openable.

Manche Farbspritzpistolen dieser Bauart haben zur Einstellung des Luftdurchsatzes eine Reguliereinrichtung, um beispielsweise für Strukturlackspritzung bzw.Some paint spray guns of this type have to adjust the Air throughput a regulating device, for example for textured paint spraying respectively.

Sprenkeln den Luftstrom auf einen geringen Durchsatz drosseln zu können. Diese Reguliereinrichtung befindet sich in einem gesonderten Luftkanal, meistens in der Nähe des Zerstäuberkopfes der Farbspritzpistole.Sprinkle to be able to throttle the airflow to a low flow rate. This regulating device is usually located in a separate air duct near the spray gun atomizer head.

Nachteilig ist dabei, daß eine zusätzliche Gehäusebohrung nötig ist. Die Aufgabe der Erfindung besteht darin, diese Gehäusebohrung einzusparen und dadurch die Herstellkosten zu senken.The disadvantage here is that an additional housing bore is necessary. The object of the invention is to save this housing bore and thereby to reduce manufacturing costs.

Zur Lösung dieser Aufgabe wird gemäß der Erfindung vorgeschlagen, koaxial zum Ventilkegel im Gehäuse der Farbspritzpistole ein Regulierküken zur Einstellung des Luftdurchsatzes drehbar anzuordnen.To solve this problem it is proposed according to the invention, A regulating plug for adjustment coaxial to the valve cone in the housing of the paint spray gun to arrange the air flow rotatable.

In weiterer Ausgestaltung der Erfindung weist das Regulierküken an seiner Stirnfläche eine Schrägfläche auf, so daß je nach Drehstellung des Regulierkükens ein quer zu ihm verlaufender Luftzufuhrkanal mehr oder weniger stark abgedeckt ist.In a further embodiment of the invention, the regulating plug has its end face on an inclined surface, so that depending on the rotary position of the regulating plug an air supply duct running transversely to it is more or less heavily covered.

Auf diese Weise wird es möglich, in einer einzigen Gehäusebohrung den Ventilkegel, der lediglich als Luftabsperrventil dient und die Luftmengenreguliereinrichtung, die als Regulierküken ausgebildet ist, unterzubringen.In this way it becomes possible in a single housing bore the valve cone, which only serves as an air shut-off valve, and the air volume regulation device, which is designed as a regulating plug to accommodate.

Um diese Konzeption mit geringstem Raumbedarf verwirklichen zu können, ist das Regulierküken als Hohlzylinder ausgeführt. In ihn ragt die Schraubenfeder hinein, die den Ventilkegel auf seinen Sitz drückt.In order to be able to realize this conception with the smallest space requirement, the regulating plug is designed as a hollow cylinder. The coil spring protrudes into it into it, which presses the valve cone onto its seat.

Anstelle der Regulierung mittels stirnseitiger Schrägfläche, die den Luftzutrittskanal bei einer Umdrehung des Regulierkükens kontinuierlich verschließt bzw. öffnet, könnte auch ein Regulierküken mit Feingewinde verwendet werden, das erst nach einer Vielzahl von Umdrehungen den Luftzutrittskanal verschließt. Ein Ausführungsbeispiel der Erfindung ist in der Zeichnung dargestellt und wird im folgenden erläutert.Instead of the regulation by means of an inclined surface at the front, which the Air inlet channel continuously closes with one turn of the regulating plug or opens, a regulating plug with a fine thread could also be used, which closes the air inlet duct only after a large number of revolutions. A Embodiment of the invention is shown in the drawing and is described below explained.

Das Gehäuse 1 der Farbspritzpistole besitzt einen Luftzutrittskanal 2, der über ein Anschlußstück 3 an eine nicht gezeichnete Preßluftquelle anschließbar ist. Der Luftzutrittskanal 2 ist mittels einer Schrägfläche 4 steuerbar, die stirnseitig an einem Regulierküken 5 angebracht ist, das als Hohlzylinder ausgebildet ist. In dem Hohlzylinder ist eine Schraubenfeder 6 untergebracht, die einen Ventilkegel 7 gegen Ventilsitz 8 des Gehäuses 1 anpreßt.The housing 1 of the paint spray gun has an air inlet channel 2, which can be connected via a connector 3 to a source of compressed air, not shown is. The air inlet duct 2 can be controlled by means of an inclined surface 4, the end face is attached to a regulating plug 5, which is designed as a hollow cylinder. In The hollow cylinder houses a helical spring 6, which has a valve cone 7 presses against valve seat 8 of housing 1.

Der Ventilkegel 7 ist über eine Stange 9 mit einem von Hand schwenkbaren Abzugsbügel 10 verbunden.The valve cone 7 is pivotable by hand via a rod 9 Trigger guard 10 connected.

Die Stange 9 ist durch eine Stopfbüchse 11 abgedichtet. Die Bohrung für die Stopfbüchse 11, der Ventilkegel 7 sowie das Regulierküken 5 liegen koaxial im Gehäuse 1, so daß die jeweiligen Gehäusebohrungen in der gleichen Spannlage der Spritzpistole bearbeitet werden können.The rod 9 is sealed by a stuffing box 11. The hole for the stuffing box 11, the valve cone 7 and the regulating plug 5 are coaxial in the housing 1, so that the respective housing bores in the same clamping position of the Spray gun can be processed.

Während bei Betätigen des Abzugsbügels 10 der Luftstrom nur. von zu nach offen steuerbar ist, kann mit dem Regulierküken 5 der Luftdruchsatz stufenlos feinfühlig eingestellt werden. Hierzu ist das Regulierküken 5 mit einem Rändelkopf 12 versehen, der außen am Gehäuse 1 anliegt. Mit einem Querstift 13 ist die Axialstellung des Regulierkükens 5 fixiert, mit einem Dichtring 14 ist es abgedichtet.While when the trigger guard 10 is operated, the air flow only. from to according to is openly controllable, the air flow rate can be steplessly adjusted with the regulating plug 5 can be set sensitively. For this purpose, the regulating plug 5 has a knurled head 12, which rests on the outside of the housing 1. With a cross pin 13 is the axial position of the regulating plug 5 is fixed and it is sealed with a sealing ring 14.
