摘要： Pumps used in liquid chromatography applications employ actuators for pressurizing and moving liquid. An actuator includes a pump head having a chamber, a gland, a movable rod extending through the gland into the chamber of the pump head, and a plunger seal disposed in the gland around the rod for sealing against fluidic leakage from the chamber. The plunger seal has an annular flange that provides an OD (outer diameter) seal against the gland. The flange defines a seal cavity. The pump head further includes an outlet port and an outlet channel. One end of the outlet channel is in communication with the outlet port and the other end of the outlet channel opens into the seal cavity of the plunger seal. The outlet channel provides a flow path for liquid in the chamber to travel towards the outlet port in response to movement of the rod.

摘要： Die erfindungsgemäße Pumpeinheit (10) weist einen besonders einfachen Aufbau auf, zu dem lediglich zwei Gehäuseteile (14,15) sowie vier Ventilverschlussglieder (37) und Pumpkolben (25,29) gehören. Die Ventilverschlussglieder (37) sind untereinander vorzugsweise gleich aufgebaut und in einer Tasche zwischen beiden Gehäuseteilen (14,15) angeordnet. Die Gehäuseteile (14,15) sind vorzugsweise mittels einer Ultraschallschweißnaht (36) dauerhaft miteinander verbunden. Die Ventilverschlussglieder (37) werden durch scheiben- oder tellerartige in sich federnde Kunststoffteile gebildet, die optional einen Mittelzapfen (42) als Montage- und Orientierungshilfe aufweisen können. Je nach Wunsch können die Ventilverschlussglieder (37) mit oder ohne Vorspannung an ihrem jeweiligen Ventilsitz (43) anliegen und besonders sicher öffnende und schließende auf geringste Strömungsgeschwindigkeiten ansprechende, leicht sterilisierbare Ventile bilden.

摘要： The invention relates to a pumping unit (14, 30) for conveying a reducing fluid, in particular for conveying a urea-water solution for reducing nitrogen oxides in an exhaust gas flow of an internal combustion engine, with a housing cover (32), a housing upper part (34) and a housing lower part (36), wherein a diaphragm (38) which is actuable by means of a drive unit (40) is accommodated between the housing cover (32) and the housing upper part (34), and a first and a second connection chamber (60, 62) are provided in the housing lower part (36). According to the invention, the conveying direction is reversible by means of an integrated valve unit (22), in particular by means of a 4/2-way valve. This reduces, inter alia, the number of components required for constructing an SCR system, thereby in particular reducing the outlay on installation and maintenance. At the same time, the availability of the SCR system is improved, in particular because of the reduced number of connecting lines. Furthermore, owing to the connecting lines no longer being necessary, the installation space which is to be kept ready and the weight are reduced.
