A housing of a liquid separation device that includes an inlet for the gas-liquid mixture and a set of integrated components, the set of integrated components includes a liquid separator vessel to separate liquid from the gas-liquid mixture, and the liquid separator vessel includes an entry port for the gas-liquid mixture, a liquid outlet port, and a gas outlet port. The set of integrated components includes a set of channels, where a wall of each channel is part of the housing, where the set of channels includes an inlet channel to guide the gas-liquid mixture from the inlet to the entry port and an outlet channel to guide gas from the gas outlet port away from the liquid separator vessel. The housing includes at least two opposite housing pieces which can be hermetically sealed together along a sealing line which is situated in a sealing face.

A housing of a liquid separation device that includes an inlet for the gas-liquid mixture and a set of integrated components, the set of integrated components includes a liquid separator vessel to separate liquid from the gas-liquid mixture, where the liquid separator vessel includes an entry port for the gas-liquid mixture, a liquid outlet port, and a gas outlet port. The set of integrated components further includes a set of channels, where a wall of each channel is part of the housing and the set of channels includes an inlet channel to guide the gas-liquid mixture from the inlet of the housing to the entry port of the liquid separator vessel and an outlet channel to guide gas from the gas outlet port away from the liquid separator vessel. The set of integrated components includes a liquid buffer tank that allows liquid to flow through an opening in the wall.

A Method for controlling the liquid injection of a compressor device or expander device. This compressor device includes at least one compressor element or expander element, whereby the element comprises a housing that comprises a rotor chamber in which at least one rotor is rotatably affixed by means of bearings, whereby liquid is injected into the element. The method comprises the step of providing two independent separated liquid supplies to the element, whereby one liquid supply is injected into the rotor chamber and the other liquid supply is injected at the location of the bearings. The separated liquid supplies are realised by means of a modular channelling piece of an injection module.

Scroll compressor with a stationary, stator scroll and a movable rotor scroll and a drive to move the rotor, whereby in each position places are formed with an instantaneous minimum opening between the rotor scroll and the stator scroll whereby at each height in a minimum opening there is a local transverse internal clearance (S), whereby at least one of the stator flanks or rotor flanks comprises an adapted flank section with an initial local stator flank deviation (&#x394;Ti, ATu) or rotor flank deviation (&#x394;Ri/ARu) that is different to zero at each point when the rotor is stationary, and during nominal operation of the scroll compressor corresponding instantaneous final local stator flank deviations (&#x394;Ti, &#x394;Tu) or rotor flank deviations (&#x394;Ri, &#x394;RU) whose absolute values are smaller.

Scroll compressor

Improved water-injected screw compressor element which mainly consists of a housing () on the one hand, confining a rotor chamber () with an inlet () on one far end and an outlet () on the other far end and in which two co-operating rotors () are provided which are bearing-mounted in the housing () with their shaft () by means of water-lubricated bearings (), characterised in that for every rotor are provided two pistons, a first piston () and a second piston () respectively, which can be each axially shifted in a guide, whereby each of these pistons () makes contact with the rotor () concerned with one side or is part of it, and makes contact with a pressure chamber () with an opposite side, in order to partly or almost entirely compensate for axial force components exerted by the compressed gasses on the rotors.
