Abstract: A compressor has a valve port plate made of a steel, through which heat of compressed gas having a relatively higher temperature is transmitted to suction gas having a relatively lower temperature. The valve port plate is nitrided or nitrocarburized for reducing heat transmission from the compressed gas to the suction gas.

Abstract: Der Hubkolbenkompressor enthält mindestens zwei Zylinder (1, 2, 3, 4) mit paarweise auf einer gemeinsamen Achse (10 bzw. 11) angeordneten Kolben (5, 7 bzw. 6, 8), die über ein ihre Kolbenstangen (12, 13 bzw. 20, 21) verbindendes Joch (14 bzw. 22) mit einem Gleitstück (15) gekoppelt sind. Das Gleitstück (15) ist über lineare Wälzlager zwischen zwei parallelen Führungsflächen (18) des Joches (14 bzw. 22) quer zur gemeinsamen Achse (10 bzw. 11) beweglich geführt und auf einem Kurbelzapfen (16) einer Antriebswelle (17) gelagert. Das Joch (14, 22) ist durch zwei voneinander getrennte, je eine der Führungsflächen (18) enthaltende und je mit einer der Kolbenstangen (12, 13, 20, 21) verbindbare Gleitschuhe (23) und einen diese umgebenden, elastisch verformbaren Spannring (26) gebildet. Durch den unter Vorspannung auf die Gleitschuhe (23) aufsetzbaren Spannring (26) sind die Gleitschuhe (23) mit einer vorbestimmten Anpresskraft über die Wälzlager gegen das Gleitstück (15) verspannbar, wodurch eine stossfreie Uebertragung der Antriebskräfte erzielt wird. Die Erfindung ist insbesondere für Kleinkompressoren geeignet.

Abstract: A scroll compressor may include a casing (110) having a sealed inner space; a drive motor (120) provided in the inner space of the casing to generate a rotational force; a rotating shaft (160) coupled to a rotor of drive motor to rotate; an orbiting scroll (150) formed of an aluminum material, and coupled to the rotating shaft to perform an orbiting movement; a fixed scroll (140) coupled to the orbiting scroll to form a compression space consisting of a suction chamber, an intermediate pressure chamber and a discharge chamber; and a rotation prevention member (170) coupled to the orbiting scroll, and formed of a sintered metal. As a result, it may be possible to prevent an Oldham ring from being worn out due to contact with the orbiting scroll. Furthermore, a weight loss portion or wear-resistant coating layer may be formed on a part of the Oldham ring, thereby suppressing a vibration noise of the compressor from being increased due to a weight increase of the Oldham ring.

Abstract: A pumping assembly is provided which is suitable for use in a variety of dosing pumps. The pumping assembly comprises a pump body with a pump bore, and a sleeve fixed within the pump bore. The sleeve has a first end, a second end and a sleeve bore. A plunger is adapted to enter the first end of the sleeve and to reciprocate within the sleeve bore. The sleeve has at least one port to allow fluid flow through a wall of the sleeve. The sleeve is formed of a harder material than the pump body.

Abstract: A valve assembly has a discharge valve member and a suction valve member. One of these valve members includes a reed valve. The reed valve has a tab which includes a localized through hardened area which provides a wear surface. The remainder to the reed valve has a lower hardness to provide fatigue strength to the reed valve.
