Abstract
Eine Pumpe (1), insbesondere eine Plungerpumpe umfasst einen Kurbeltrieb (3), der einen in einem Gehäuse angeordneten und in einer Aufnahme (51) geführten Plunger (5) oszillierend antreibt, und einem an dem Gehäuse (2) festgelegten Pumpenkopf (6) zur Leitung des von einem Saugraum (9) abgezogenen mit Druck beaufschlagten Fluids, wobei das Gehäuse (2) den Kurbeltrieb (3) und den Plunger (5) umgibt. Erfindungsgemäß sind am Plunger (5) elastische Dichtmittel (7) festgelegt, die eine druckdichte Abdichtung zu einem unteren den Kurbeltrieb (3) enthaltenden Gehäuseraum (13) bereitstellen. Dadurch kann in dem Gehäuse ein Zwischenraum (12) mit Luft gefüllt sein, der hermetisch von dem unteren Gehäuseraum (19) mit dem Kurbeltrieb (3) abgetrennt ist. A pump (1), in particular a plunger pump, comprises a crank mechanism (3) which oscillates a plunger (5) arranged in a housing and guided in a receptacle (51), and a pump head (6) fixed to the housing (2). for guiding the pressurized fluid drawn off from a suction chamber (9), the housing (2) surrounding the crank mechanism (3) and the plunger (5). According to the invention, elastic sealing means (7) are attached to the plunger (5), which provide a pressure-tight seal to a lower housing space (13) containing the crank mechanism (3). As a result, an intermediate space (12) in the housing can be filled with air, which is hermetically separated from the lower housing space (19) with the crank mechanism (3).
