Bei hohen Kolbengeschwindigkeiten entstehen bauliche Schwierigkeiten, den erforderlichen Durchströmungsquerschnitt bei den Ein- und Auslafsorganen zu erzielen, ohne auf eine unerwünschte Gröfse der .Ventilkästen zu gelangen. At high piston speeds, structural difficulties arise in finding the required flow cross-section at the inlet and to achieve outlet organs without reaching an undesirable size of the .Ventilkäse.

Die in Nachstehendem beschriebene Anordnung bezweckt nun, selbsttätige Ein- und, Ausiafsorgaiie bei Gebläsemaschinen, Gom-, pressoren und Pumpen so anzuordnen, dafs cincstlicils ein möglichst geringer Raum durch die Ventile selbst und ihre Ventilkiisten eingenommen 'und anderenteils eine leichte Zugänglichkeit der Ventile gcwährlcitet wird. Ferner wird angestrebt, die Ventilkasten und die darin enthaltenen Ventile derartig zubauen, dafs beide ohne jede Aenderung entweder als Einlafs- oder Auslafsorgane verwendet werden können, wobei sowohl die Ventilkasten als auch . die Ventile eine insbesondere für die billige Massenherstellung geeignete Form erhalten sollen. The purpose of the arrangement described below is to enable automatic input and Ausiafsorgaiie for blower machines, Gom-, to arrange pressors and pumps in such a way that there is as little space as possible through them the valves themselves and their valve boxes occupied 'and on the other hand easy accessibility the valves are guaranteed. Furthermore, the aim is the valve box and to build the valves contained therein in such a way, that both are used, without any change, either as inlet or outlet organs can, with both the valve box as well. the valves one in particular for the cheap mass production should be given suitable shape.

Im Allgemeinen kann jedes selbsttätige Ventil in der zu beschreibenden Weise angeordnet werden, doch sind hierzu Ringventile besonders geeignet, und in erster Reihe das im D. R. P. 87267 beschriebene Lenkerventil.In general, each can be self-acting Valve can be arranged in the manner to be described, but are ring valves for this purpose particularly suitable, and in the first place the handlebar valve described in D. R. P. 87267.

Zu diesem Zwecke werden die für sich gesonderten Saug- oder Druckventile zu Ventilgruppen zusammengelegt, und zwar in der Weise, dafs abwechselnd ein Ventilsitz und ein Ventilfönger auf einander zu liegen kommen. Vortheilhafterwcise sind die Ventilsitze als Doppelsitze ausgebildet, d.h. beide Ventilseiten stellen Ventilsitze dar, so dafs der zwischen zwei solchen Doppelsitzen liegende Fänger gleichzeitig als Hubbegrenzung für zwei Ventile dient. Die Ventilsitze sind hohl oder haben am Umfange eine ringförmige Aussparung und tritt das anzusaugende oder (beim Druckorgan) das zu fördernde Medium vom äufseren Umfange in den hohlen Doppelsitz und sodann durch das eigentliche Abschlufsorgan. Die einzelnen Ventilgruppen können durch eine centrale Hauptschraube zusammengehalten werden, sind aber sonst unter einander mechanisch nicht verbunden, so dafs nach Herausnahme dieser Hauptschraube die betreffende Ventilgruppe in einzelne (bis auf die Endstücke) gleiche Sitz- und Fangerelemente zerfällt. Der Ventilkasten, welcher zur Aufnahme einer solchen Ventilgruppe dient, ist durch Zwischenwände in einzelne Kammern getheilt, welche jedoch eine kreisförmige Bohrung zur Aufnahme der Ventile bezw. der Ventilgruppe haben. Nach dem Einsetzen der Ventile sind diese Sitz- und Fängerkammern von einander getrennt und stehen nur mehr durch das bewegliche Abschlufsorgan unter einander in Verbindung.For this purpose, the suction or pressure valves, which are separate in themselves, become valve groups folded, in such a way that a valve seat and a valve fan come to rest on top of each other. Beneficial way the valve seats are designed as double seats, i.e. place both valve sides Valve seats represent, so that the catcher lying between two such double seats simultaneously serves as a stroke limiter for two valves. The valve seats are hollow or have a circumference an annular recess and the to be sucked in or (in the case of the pressure element) that enters conveying medium from the outer circumference into the hollow double seat and then through the actual closing body. The individual valve groups can through a central Main screw are held together, but are otherwise not mechanically among each other connected, so that after removing this main screw, the valve group in question in individual (except for the end pieces) the same seat and catcher elements disintegrate. The valve box, which is used to accommodate such a valve group, is separated by partitions Divided chambers, which, however, have a circular bore for receiving the valves respectively of the valve group. After inserting the valves, these are seat and Catcher chambers separated from each other and are only available through the movable closure organ in connection with each other.

Die Kammern gleicher Art sind unter einander in Verbindung, und zwar entweder mit dem Cylinderinneren oder mit dem Cylindcräufseren. Wird nämlich eine Ventilgruppe als Saugorgan verwendet, so stehen die Ventilsitzkammern bezw. die hohlen Ventilsitze selbst mit dem Cylinderäufseren in ständiger Verbindung und die Fängerkammern (durch Schlitze am Cylindermantel oder Deckel) mit dem Cylihderinneren. Wird umgekehrt dieselbe Ventilgruppe und derselbe Ventilkasten als Druckorgan verwendet, so ist das Cylinderinncrc (durch Schlitze am Cylindermantel oder Deckel)The chambers of the same kind are connected to one another, either with the inside of the cylinder or with the cylinder sera. If a valve group is used as a suction element, the valve seat chambers are located respectively the hollow valve seats themselves are in constant contact with the outside of the cylinder and the catcher chambers (through slots on the cylinder jacket or cover) with the cylinder interior. Conversely, the same valve group and the same valve box are used as the pressure device is used, the cylinder interior is used (through slots on the cylinder jacket or cover)

Claims

bezvv with dun valve chambers with the hollow valve seats in connection, while the catcher chambers are connected to the Cylindcräufersercn. Such valve groups and valve boxes are advantageously arranged in blower machines, compressors and pumps in such a way that the axis of the valve group crosses the cylinder axis at right angles. However, the two axes can also be parallel. In the sanctifying drawing Fig. Ι shows a front view respectively. a cross section through the cylinder and the two valve chambers of a blower assembly; Fig. 2 shows in part one. Longitudinal section, partly a longitudinal view of the same cylinder. 3, 4 and 5 are longitudinal and cross sections through the valve box with the valves. In the double-acting cylinder α, the piston b moves with the piston rod c. The air inlet to the cylinder takes place through the two Saiigvenfilkästen d and e, while the delivery takes place through the pressure valve boxes_ / and g. The suction valve boxes d and e are connected to the inside of the cylinder through slots / ', the pressure valve boxes through the same slots i. The suction or pressure valve groups are (Fig. 3, 4 and 5) composed in the manner described from seat and catcher elements Ic and / and held together by a central Hauptscliraubc. Air enters the valve boxes through the inlet valve slits. the inlet chamber spaces c and through the recesses / »the hollow valve slits in the way of the closing element q into the valve catcher chambers u. From here, depending on the use of the valve group as a suction or pressure device, the air passes through the openings; the valve boxes either through the slits Ii in d ^ n cylinder or \ ziir pressure line. The covers close the valve boxes on the outside; after removing such a cover, the valve group in question can be removed as a whole in the simplest possible manner. The valves can also be arranged on the cylinder lids, in a similar way as is now done with controlled suction slides. In the case of pumps in particular, several suction or pressure valve groups can also be arranged parallel to one another and to the cylinder axis or also crossed to one another. In single-cylinder pumps, easy accessibility is achieved if both or only one of the valve groups (such as the pressure valves) are placed transversely to the piston axis, as in FIGS If the pressure valve group were too unwieldy, two or more groups of a valve category can be arranged in one of the ways mentioned above! Patent-A ν Proverbs:
