  • Publication number: 20220186729
    Abstract: An element for compressing or expanding a gas including a rigid housing (2) containing an internal chamber; a rotor (3a, 3b) situated in the internal chamber and comprising a rotor shaft (4a, 4b); one or more bearings (7) in which the rotor shaft (4a, 4b) is bearing-supported, wherein the rotor (3a, 3b) with its rotor shaft (4a, 4b) is rotatably mounted with respect to the housing (2) by means of these bearings (7), wherein the rotor (3a, 3b) is mounted with one or more clearances with respect to a wall (5) of the internal chamber, and the element (1) is provided with a separate yielding component (10) which is positionally adjustable with respect to the housing (2) in such a way that at least one of the clearances can be acted upon, wherein the separate yielding component (10) is not directly attached to the rotor (3a, 3b).

  • Publication number: 20220042502
    Abstract: A piston compressor, comprising at least one piston compressor element (3) that is provided with a housing (8) with a compression chamber (13) in which a piston (10) is arranged movably back and forth in an axial direction (X-X?) between an upper dead point and a lower dead point by means of a drive shaft (5) driven by a rotary motor (6), and in which between this drive shaft (5) and the piston (10), a kinematic transmission (20) is provided for the primary drive of the piston (10), characterized in that the piston (10) is provided with a complementary drive (25) in the form of an electromagnetic linear drive.

  • Publication number: 20210396229
    Abstract: Positive displacement machine such as a compressor, expander, pump or the like, for displacing a gaseous or liquid medium, the machine containing an element with at least one inlet and at least one outlet for the medium and at least two cooperating driven moving parts. The mutual periodic movement of the moving parts displaces the medium from the inlet to the outlet. Each of the at least two driven cooperating moving parts is provided with its own individual drive. The element is provided with a kinematic synchronisation coupling between the at least two cooperating moving parts for the mutual kinematic synchronisation of their movements.

  • Publication number: 20210372384
    Abstract: A piston compressor containing a housing with a compression chamber in it, having an inlet and an outlet and a piston arranged movably back and forth in an axial direction in the compression chamber between an upper dead point and a lower dead point, delimited by a kinematic mechanism with which the piston is connected. The drive is formed exclusively by an electromagnetic linear drive of the piston.

  • Patent number: 11015647
    Abstract: A device includes a bearing-in-bearing with an inner ring, an intermediate ring and an outer ring. Between the inner ring and the intermediate ring and between the intermediate ring and the outer ring, inner roller elements, and outer roller elements, are attached, respectively. The bearing-in-bearing is attached between two components that can rotate in relation to each other, a shaft and a housing, of which one component is or can be connected to a drive. A transmission is provided between the intermediate ring and the driven component in order to drive the intermediate ring. The transmission is a contactless transmission.

  • Patent number: 10935073
    Abstract: A bearing damper element includes a ring mounted between a rotating object and a supporting object which supports the ring. The ring includes at least three slits through the thickness of the ring in the axial direction and at a distance of the radial inner and outer surface of the ring. At least half of the slits have one or more damping parts with a maximum width of 0.5 millimeters, whereby the damping parts are concentric and do not overlap.
