ander angeordneten Fingern eines gehäusefesten, Weitere Vorteile ergeben sich aus den übrigen Anzum Abstützen der Ventilfeder dienenden Füh- xo Sprüchen.1. Valve with a plate-shaped valve- In another known valve, the link is that the housing parts provided with an annular bead as a valve seat work together and the valve spring is designed like a bow and therefore cannot hold the valve seat , the valve member for guiding the valve member and for the lateral between on its circumference at a distance from one-holding the spring (DT-PS 853 367).
Fingers arranged on the other side of a housing fixed to the housing. Further advantages result from the other Füh- xo sayings used to support the valve spring.

Der Pumpenkolben kann mittels eines Halters 17 ein Sieb 18 angebracht, das bis in Haftnähe an das plattenförmige Ventilglied mindestens die öffnung des Ansaugnippels 10 überherangeführt werden und dessen Öffnungsvorgang 50 deckt.The present invention is also based on the object of the guide member 7 establishing a plate-shaped valve member, arranging a valve of the aforementioned type of a piston 12, the dispensing pump opposite the piston 2. This task is graded according to it. According to the invention, a valve spring 13 is achieved between the guide member 7 and the plate-shaped valve member 12. The guide member for the 40 clamped, which seeks to hold the plate-shaped valve member valve member on the annular bead 11 for the purpose of the passage of the KoI,
bens formed in an advantageous manner ring-shaped. A laterally to which the guide member 7 receives-This results in a simplified, easy and mend chamber connected channel is through cheaply produced valve design for a piston pump with a ball 14 and a spring 15, in which the plate-shaped valve member does not monitor a check valve , which needs a precise guide, since between its Um- screw 16 is to be kept in the working position.
catch and that of the adjacent body a large amount to the piston housing 1 is on its inlet side play can be present. A screen 18 can be attached to the pump piston by means of a holder 17, which sieve 18 is guided over at least the opening of the suction nipple 10 up to the proximity of the plate-shaped valve member and covers the opening process 50 thereof.
rungsglied ist vielmehr auf seiner vom Ventilglied 65 Das in der Zeichnung dargestellte Saugventil kann abgewandten Seite geschlossen ausgebildet, so daß auch bei anderen Kolbenpumpen verwendet werden.A known valve of the aforementioned type has valve member 12 from the annular bead 11 and although a plate-shaped valve member and a finger 55 directly follow the movement of the piston 2, until they come to a gladly provided guide member that is used to guide the stop parts 9 of the fingers 8 sits on. The valve member and the check valve 14 for supporting the valve spring remains closed. Serves. However, the known valve is not designed for the end of the pressure stroke, and the plate-shaped valve interaction with a piston pump is provided by the valve spring 13 and the pressure in the valve and is also not designed for this purpose. The working space of the piston 2 on the annular bead 11 of the known valve has no opening, and the pressure medium conveyed by the piston, for the passage of a piston, which is therefore also especially liquid, does not flow over the non-return valve to save space can be brought up to the valve 14 to the pressure side in the pump valve member, not shown. The guide housing of the radial piston pump,
Rung member is rather on its from the valve member 65. The suction valve shown in the drawing can be closed on the opposite side, so that it can also be used in other piston pumps.
