    摘要： The invention relates to a debris trap (40) for capturing debris flowing in a stream of liquid, the debris trap (40) comprising
    - a housing (42) having a space (44) inside the housing (42)
    - a fluid inlet channel (46) in connection with the space (44),
    - a fluid outlet channel (48) in connection with the space (44), the fluid out-let channel (48) comprising a fluid outlet port (50),
    - a float member (52),
    - a guide means (54) configured to guide the float member's (52) movement as liquid level in the space (44) changes when in use,
    - a stopper (53) in connection with the fluid outlet port (50) configured to stop the float member's (52) movement as liquid level in the space (44) raises,
    - the fluid outlet port (50) which, when the float member (52) is against the stopper (53), is configured to remain partially open.
    The invention relates also to a priming assembly (10) comprising the debris trap (40).

    摘要： An inexpensive and simple-to-control solution for degassing liquid media is to be provided by way of a pump for delivering and degassing a liquid and having a pump housing with a pump inlet and a pump outlet, wherein a pump impeller which is connected to a drive motor is provided within the pump housing and wherein a nozzle is provided in a degassing device. This is achieved with a pump by virtue of the fact that the at least one nozzle (7) is arranged in the pump inlet (4), wherein an entry of liquid into an interior (6) of the pump housing (2) is possible only through the nozzle (7), and the degassing device has a control device which is connected to the drive motor (3).
