Abstract: The present disclosure generally relates to a pumping element of a fuel pump for an internal combustion engine wherein the pumping element comprises a pumping chamber and a check valve assembly having a first insert including an angled passage in flow communication with a fuel outlet, and a second insert being disposed adjacent the pumping chamber, the second insert including a central bore in flow communication with a fuel inlet, a plurality of through holes in flow communication with the pumping chamber.

Abstract: A luminaire includes a terminal block that receives power from a power source, a light source power supply electrically coupled to the terminal block and to a light source, a power converter electrically coupled to the terminal block and to a power over Ethernet injector, a camera coupled to the power over Ethernet injector, and a transceiver electrically coupled to the power converter. The power over Ethernet injector can supply power to and receive data from the camera. The transceiver is also coupled to the power over Ethernet injector and can communicate data to and receive data from the camera.
