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.

Abstract: Disclosed is a flow heater with a housing having an inlet opening and an outlet opening, a heating plate delimiting a flow path for fluid to be heated to flow from the inlet opening to the outlet opening, and a flow guidance plate that is arranged inside the housing, the flow guidance plate extending along the heating plate at a distance from it thereby delimiting the flow path.

Abstract: An engine accessory with a wrap spring clutch, which is configured for selectively transmitting rotary power between a drive member and a shaft, and an actuator that is configured to selectively control the clutch. The actuator has first and second rotary flux elements, a clutch control ring and an electromagnet. The first rotary flux element is rotatably coupled to the drive member and has a plurality of first teeth that are spaced circumferentially about the rotary axis. The clutch control ring is rotatable about the rotary axis and is coupled to the tang of the wrap spring. The second rotary flux element is rotatably coupled to the clutch control ring. The second rotary flux element has a plurality of second teeth that are spaced circumferentially about the rotary axis. The electromagnet is selectively operable to generate a magnetic field that is transmitted between the first and second teeth.

Abstract: A fan penetration fixture consisting of a threaded shaft and a lock nut design. The fixture is designed to take the place of the fan clutch on a fan drive assembly in the vehicle being tested for a desired cooling system performance characteristic at each possible fan penetration. The threaded shaft portion of the fixture bolts to the fan hub. The desired fan is then bolted to the lock nut portion of the fixture. The lock nut can be positioned at any point along the threaded shaft to achieve a desired fan penetration.
