    Abstract: The present invention refers to a reciprocating compressor provided with an arrangement of suction valves and, more particularly, a reciprocating compressor which, capable of operating with at least two suction lines having different working pressures, is made up of an arrangement of valves comprising at least two "orifice valve" sets. One of these sets provides a semi- commanded valve, whereas the other set provides an automatic valve. The core of the invention is related to the fact that said "orifice valve" sets are disposed on different components of the reciprocating compressor.

    Abstract: A positive displacement fluid pump with increased service life is described. The positive displacement pump includes a plunger, a suction bore and a discharge bore. The plunger, the suction bore and the discharge bore form a pumping chamber. The diameter of the suction bore is greater than the diameter of the discharge bore. The difference in the diameters of the suction bore and the discharge bore allows for less fluid to be discharged through the discharge valve than what is being put into the bore through the suction valve and helps in increasing the service life of the pump. A method of operation of such a positive displacement pump is also provided.

    Abstract: Bei dynamisch beanspruchten Bauteilen, insbesondere Hydraulikzylindern, die mindestens eine Schweißnaht aufweisen, kann mit der Zeit eine Ermüdung der Schweißnaht und ein damit einhergehender Festigkeitsverlust auftreten, insbesondere dann, wenn die Wurzel der Schweißnaht stark belastet wird. Häufige Ursache für Materialversagen sind z.B. Haarrisse im Bereich der Wurzel. Um die Festigkeit von rotationssymmetrischen, geschweißten Bauteilen zu verbessern, wird vorgeschlagen, dass an einem ersten Teil (2; 4) und/oder an einem zweiten Teil (3; 5) des Bauteils, die über die Schweißnaht (10) miteinander verbunden sind, in einem an die Schweißnaht (10) angrenzenden Bereich ein verschmälerter Steg (7) ausgebildet wird, wobei die Wandstärke (t 1 , t 2 ) des ersten bzw. zweiten Teils (2;4, 3;5) im Bereich des verschmälerten Stegs (7) kleiner ist als die Tiefe (t s ) der Schweißnaht (10). Hierdurch kann der Kraftfluss wenigstens zum Teil an der Wurzel (11) vorbeigeführt werden, so dass die Schweißverbindung (10) weniger stark beansprucht wird.
