  • Patent number: 9151186
    Abstract: An oil-laden gas stream flows axially through a tube shaft formed with at least one radially throughgoing inner oil-discharge port and, axially downstream therefrom, with at lest one radially throughgoing inner gas-discharge port. A bearing supports the tube shaft for rotation about the axis and is formed axially level with the ports with respective radially throughgoing outer oil-discharge and gas-discharge ports. An oil separator inside the tube shaft axially between the oil-discharge ports and the gas-discharge ports is oriented to deflect oil particles from the stream radially outward such that the oil flows out through the inner and outer oil-discharge ports and the gas stream can flow downstream out through the gas-discharge ports.

  • Patent number: 8707579
    Abstract: In a method for operating an adsorption dryer, a process air flow, generated by at least one blower, is routed at least at times through an adsorption apparatus and over a textile goods in care during a textile care process in a “dry” operating mode to thereby charge a reversibly dehydratable adsorbent of the adsorption apparatus with moisture. A charge state of the adsorbent with water is detected and is displayed at least after the end of the “drying” textile care process. The absorbent is desorbed at least in part during a subsequent, selected and started textile care process in a “refresh” operating mode, and the desorbed moisture is routed as a moist process air flow into a receptacle for refreshing textile goods which are stored or hung in a stationary manner.

  • Patent number: 8657907
    Abstract: A cam shaft has a tubular part extending longitudinally along an axis and a helical body fixed in the tubular part and having a first helical passage extending between an inlet end where a first pressure is present and an outlet end where a second pressure is present. This helical body forms an oil separator between the inlet and outlet ends. A flow-blocking element at the inlet end moves as a function of a pressure differential between the first and second pressures to open and close the first helical passage.

  • Publication number: 20140007736
    Abstract: The invention relates to a shaft, particularly a cam shaft (1), comprising a hollow shaft section (10) with at least one inlet opening (11a, 11b) for evacuating a gas through said hollow shaft section (10), and comprising a splash-guard device (4) arranged in the region of the radial inlet opening (11a, 11b) on the hollow shaft section (10). According to the invention, the splash-guard device (4) has a radially exposed cover with radial passage openings (8) and protrusions between said passage openings (8). The protrusions can, in particular, be in the form of ribs (9). To be published with FIG. 3.

  • Patent number: 8496721
    Abstract: A hollow body includes an integrated oil separator unit, a swirl generator located in a cavity of the hollow body, at least one first supply opening in the camshaft case for introducing gas that is charged with oil into the cavity, and at least one discharge opening for carrying away separated oil and for carrying away gas that has been cleaned of oil. The swirl generator also has elements that are used to variably influence the pressure prevailing at a predetermined point in the cavity.

  • Publication number: 20130118357
    Abstract: The invention relates to a hollow body having a hollow cylindrical design at least in some regions, in particular to a camshaft (1), comprising an oil separation device that is integrated in a cavity of the hollow body, wherein a first pressure (p1) is present on an outlet side (5) of the oil separation device, and wherein a second pressure (P2) is present on an inlet side (4) of the oil separation device. According to the invention, the oil separation device is designed as a multiple thread worm body (2) which is connected to the hollow shaft section in a rotationally fixed manner. In addition, a shut-off element (6, 6?) is provided, which on the inlet side (4) opens or closes the access to at least one worm channel (3b, 3c) of the multiple thread worm body (2) depending on the pressure difference (?p) between the second pressure (p2) and the first pressure (P1).
