Abstract
Eine handbetätigte hydraulische Pumpe umfasst ein Grundgehäuse 1, das ein Reservoir 2 mit transparenten angeschrägten Wänden 80 und eine Pumpe 3 zum Pumpen eines Fluides aus einem Reservoir 2 zu einer zweiten Kammer 4 und einen Messpunktauslass 5 umfasst. Ein Aktivieren der Pumpe wird über ein Zusammendrücken von Griffen 3, 4 vorgenommen, um einen Kolben (nicht gezeigt) innerhalb eines Pumpengehäuses 61 zu betätigen. Die Pumpe umfasst des Weiteren einen kombinierten Druckeinstell- und Druckablassmechanismus 6, um geringfügige Veränderungen des Druckes in der zweiten Kammer 4 vorzunehmen. Der Mechanismus 6 wird durch konzentrische Knöpfe 29, 34 betätigt. Die Pumpe umfasst des Weiteren ein eingebautes Überdruckablassventil 7, um einen Überdruck in der Kammer 4 abzulassen, wobei das Ablassventil über den gesamten Druckbereich betriebsfähig ist, bei denen die Pumpe arbeitet. Ein Einlass 13 und Auslässe 5, 19 weisen Siebe auf, die ein durch sie hindurch fließendes Fluid filtern.A manual hydraulic pump comprises a base housing 1 which includes a reservoir 2 with transparent tapered walls 80 and a pump 3 for pumping a fluid from a reservoir 2 to a second chamber 4 and a measuring point outlet 5. Activation of the pump is accomplished by squeezing handles 3, 4 to actuate a piston (not shown) within a pump housing 61. The pump further includes a combined pressure adjusting and depressurizing mechanism 6 for making slight changes in the pressure in the second chamber 4. The mechanism 6 is actuated by concentric knobs 29, 34. The pump further includes a built-in pressure relief valve 7 for venting excess pressure in the chamber 4, the drain valve being operable over the entire pressure range at which the pump operates. An inlet 13 and outlets 5, 19 have screens which filter a fluid flowing therethrough.
