  • Patent number: 12117209
    Abstract: Disclosed is a flow heater with a housing having an inlet and an outlet. A flow passage for liquid that is to be heated runs from the inlet to the outlet. A heating plate is arranged as wall of a heated section of the flow passage. A bypass passage is provided in parallel to the heated section of the flow passage in order to guide any gas bubbles contained in the liquid from the fluid inlet to the fluid outlet without passing through the heated section of the flow passage.

  • Patent number: 8851257
    Abstract: The present invention relates to a fluid accumulator chamber (1) of a fluid clutch device having an inner boundary wall (2) which runs around a central axis of rotation (M), having an outer boundary wall (3) which runs around axis of rotation (M), and having at least one filling opening (4) arranged in the outer boundary wall (3), wherein the outer boundary wall (3) has, at the location of the filling opening (4), a maximum spacing (R1) to the central axis (M), which spacing decreases continuously to a point (P) of minimum spacing (R3) to the central axis (M).
