Abstract

The control valve fits in a cylindrical sleeve (1). It has one opening on the end of the sleeve and two in line radial openings on the side of the sleeve. The sleeve is fitted with two seal rings (3) and (4) one at the base of the sleeve and the other at the top. The valve (2) is cylindrical and fits the bore of the sleeve. The end of the valve has a conical surface which comes into contact with the edge of the lower seal when the valve is closed. the valve may be arranged in series with other similar valves on the same stem.

Description

Kontaktdruck- und SperrventilContact pressure and shut-off valve

Beschreibung Es sind Systeme bekannt, die es neben der Hauptfunktion als Druck- bzw. Sperrventil mittels mechanisch gekuppelter Betätigungsmechanismen ermöglichen, Drücke und Schaltpositionen für hydraulische und pneumatische Systeme zu überwachen.Description There are systems known that have it in addition to the main function as a pressure or shut-off valve by means of mechanically coupled actuating mechanisms enable pressures and switching positions for hydraulic and pneumatic systems to monitor.

Die Überwachung erfolgt dabei entweder über mechanische, induktive oder kapazitive Schalter.The monitoring takes place either via mechanical, inductive or capacitive switches.

Die Nachteile dieser Systeme liegen darin, daß neben dem hohen technischen Aufwand die Geräte aufgrund fertigungsbedingter Ungenauigkeiten, nicht exakt arbeiten.The disadvantages of these systems are that in addition to the high technical Effort the devices do not work exactly due to manufacturing-related inaccuracies.

Der vorliegenden Erfindung liegt nun die Aufgabe zugrunde, unter Fortfall mechanischer Kupplungsglieder und elektrischer Endschalter eine elektrische Signalgabe bei einer bestimmten Schaltposition oder Schaltstellung zu erreichen.The object of the present invention is now to be omitted mechanical coupling links and electrical limit switches give an electrical signal to be reached at a certain switch position or switch position.

Erfindungsgemäß wird die Aufgabe dadurch gelöst, daß das bewegliche Schalt element des Ventils gleichzeitig als elektrisches Schaltelement ausgebildet ist, wobei das Schalt element gegen das Gehäuse oder eine Führungshülse elektrisch so isoliert ist, daß nur bei Erreichen einer definierten Schaltposition eine Kontaktgabe zum Gehäuse oder zur Führungshülse erfolgen kann.According to the invention the object is achieved in that the movable Switching element of the valve simultaneously designed as an electrical switching element is, the switching element against the housing or a guide sleeve electrically is so isolated that contact is only made when a defined switching position is reached to the housing or to the guide sleeve.
