Abstract

Fluid inlet (1) consists of tubular body with outer winding (1') to screw into front opening of hydraulic pressure control. Inlet is closed at its free end and has radial through holes (2) for liquid. Holes are covered by cylindrical filter screen (3) on outside. Holes are formed as ring of bores. Filter screen is supported on studs (4) located between the holes on same level as bores.

<Desc/Clms Page number 1>  <Desc / Clms Page number 1>   Die Erfindung betrifft einen Fluideinlassteil für Druckfluidsteuereinrichtungen, insbesondere für Hydraulik- und Pneumatikventile, der einen im wesentlichen rohrförmigen Körper mit einem Au- ssengewindeabschnitt zum Einschrauben in eine stirnseitige Öffnung der Druckfluidsteuereinrichtung aufweist, wobei der Einlassteil an seinem freien Stirnende geschlossen und mit radialen Druckfluiddurchtrittsöffnungen versehen ist, die von einem auf die Aussenseite des Fluideinlassteiles aufgebrachten zylindrischen Filtersieb überdeckt sind.  The invention relates to a fluid inlet part for pressurized fluid control devices, in particular for hydraulic and pneumatic valves, which has an essentially tubular body with an external thread section for screwing into an end opening of the pressurized fluid control device, the inlet part being closed at its free end and provided with radial pressurized fluid passage openings which are covered by a cylindrical filter screen attached to the outside of the fluid inlet part. Bei Druckfluideinlassteilen dieser Art, bei denen die Notwendigkeit besteht, das durchtretende Fluid zu filtern, hat sich in der Praxis gezeigt, dass die bekannten Konstruktionen durchwegs mit der Gefahr der Verformung unter dem Mediumdruck und des dadurch bedingten Zusetzens verbunden sind.  In the case of pressurized fluid inlet parts of this type, where there is a need to filter the fluid passing through, it has been shown in practice that the known constructions are all associated with the risk of deformation under the medium pressure and the resulting clogging. Die Erfindung zielt darauf ab, diesen Nachteil zu vermeiden, und erreicht dies bei einem Flui- deinlassteil der einleitend angegebenen Art dadurch, dass die Durchtrittsöffnungen dem freien Stirnende des Einlassteiles benachbart in Form eines Kranzes von Bohrungen ausgebildet sind und das Sieb sich an in Umfangsrichtung zwischen den Durchtrittsbohrungen des Fluideinlassteiles verlaufenden Stegen, die in der Ebene der Durchtrittsbohrungen angeordnet sind, abstützt.  The invention aims to avoid this disadvantage and achieves this in the case of a fluid inlet part of the type specified in the introduction in that the passage openings are formed in the form of a ring of bores adjacent to the free front end of the inlet part and the strainer is arranged in the circumferential direction between supports the through bores of the fluid inlet part, which are arranged in the plane of the through bores. Durch diese Konstruktion wird jegliche unerwünschte Verformung des Filtersiebs durch das Druckmedium vermieden und eine lange Betriebsdauer der Fluidsteuereinrichtung sichergestellt.  This construction avoids any undesired deformation of the filter screen by the pressure medium and ensures a long service life of the fluid control device. Die Erfindung wird nachfolgend an einem Ausführungsbeispiel unter Bezugnahme auf die Zeichnung näher erläutert, die einen Axialschnitt durch einen Fluideinlassteil gemäss der Erfindung zeigt.  The invention is explained in more detail below using an exemplary embodiment with reference to the drawing, which shows an axial section through a fluid inlet part according to the invention. In einen rohrförmigen Endabschnitt einer nicht näher gezeigten Druckfluidsteuereinrichtung D, z. B. ein Hydraulikventil, ist ein Fluideinlassteil 1 eingeschraubt, der einen im wesentlichen rohrförmigen Körper mit einem Aussengewindeabschnitt l'aufweist und an seinem freien Stirnende 1" geschlossen ist. Diesem Ende benachbart sind radiale Druckfluiddurchtrittsöffnungen 2 vorgesehen, die von einem auf die Aussenseite des Fluideinlassteiles 1 aufgebrachten zylindrischen Filtersieb 3 überdeckt sind, welches sich an zentralen Stegen 4 des Fluideinlassteiles 1 abstützt.  In a tubular end portion of a pressure fluid control device D, not shown, z. For example, a hydraulic valve, a fluid inlet part 1 is screwed in, which has a substantially tubular body with an externally threaded section 1 ′ and is closed at its free end face 1 ″. Adjacent to this end are radial pressure fluid passage openings 2, which extend from one to the outside of the fluid inlet part 1 applied cylindrical filter screen 3 are covered, which is supported on central webs 4 of the fluid inlet part 1. Diese Stege verlaufen in Umfangsrichtung zwischen den Durchtrittsöffnungen 2 und verhindern eine Verformung des Siebes unter dem Druck des in Richtung des Pfeiles P zuströmenden Oruckflui- des. **WARNUNG** Ende CLMS Feld Kannt Anfang DESC uberlappen**.  These webs run in the circumferential direction between the passage openings 2 and prevent the strainer from being deformed under the pressure of the pressure fluid flowing in the direction of the arrow P. ** WARNING ** End of CLMS field knows overlap beginning of DESC **.
