A fluid end assembly comprising a plurality of fluid end sections positioned in a side-by-side relationship. Each fluid end section comprises a housing having a bore formed therein for housing a reciprocating plunger. Fluid is prevented from leaking around the plunger by a packing seal assembly. The packing seal assembly comprises one and only one packing seal.

The present invention refers to a reciprocating compressor cylinder cover and, more particularly, to a cylinder cover provided with at least one discharge chamber comprising a compact construction concept, able to guarantee an application in reciprocating compressors of different capacities, with hermetic housings provided with different internal volumes.

An oil separator for a compressor comprising a tank and a lid for the tank, which comprises, in an integral manner, a valve body defining an outlet duct of the separator, a head of a coalescence filter, a body of an anti-condensate valve, a body of a minimum pressure valve and the relative connection ducts.

The invention relates to a hermetically encapsulated refrigerant compressor comprising a housing having a bottom part and a cover, the cover being connectable to the bottom part, an electrical connection piece penetrating the housing and a piston pump which is arranged in the housing and can be electrically connected to a control unit via the connection piece. The cover of the housing has a through opening in which the electrical connection piece is arranged. The housing is configured in such a way that, when the housing is open, the piston pump can be inserted into the cover of the housing and is connectable to the electrical connection piece.

A compressor system includes: a first compressor including a first casing having a cylindrical shape, and a first bundle capable of being inserted into and pulled out from the first casing in an axial direction of the first casing; and a second compressor including a second casing having a cylindrical shape, and a second bundle capable of being inserted into and pulled out from the second casing in an axial direction of the second casing. The first and second compressors are arranged to face each other to cause pullout directions of the respective bundles to be opposite to each other. A maintenance space shareable for insertion and pullout operations of the first bundle and insertion and pullout operations of the second bundle is interposed between the first bundle and the second bundle, and is available for the bundle under the insertion and pullout operations.
