Abstract: The powder injector according to the invention with quick coupling comprises an injector housing (5), which has a powder inlet (12) and supply air inlets (5.15, 5.16, 5.17) and in which a drive nozzle (7) and a collection nozzle (8) are arranged. The powder injector additionally comprises a line connection block (6), which has connections (15, 16, 17) for supply air lines and the supply air outlets (6.15, 6.16, 6.17). The powder injector furthermore comprises a quick closure (9), by means of which the line connection block (6) can be fastened to the injector housing (5) and the supply air outlets (6.15, 6.16, 6.17) of the line connection block (6) can be connected to the supply air inlets (5.15, 5.16, 5.17) of the injector housing (5).

Abstract: A measuring apparatus for measuring a coating powder mass flow rate generable by compressed gas in a powder line includes a control and evaluation unit, which is configured and operable such that it can switch between an offset mode and an operating mode. In the offset mode, the control and evaluation unit ensures that a setting device applies compressed gas to the powder line and prevents the coating powder flow in the powder line, and that a pressure sensor then detects the pressure in the powder line. The control and evaluation unit interprets the detected pressure as an offset pressure value. In the operating mode, the control and evaluation unit ensures that the setting device enables the coating powder flow in the powder line, and then determines the coating powder mass flow rate flowing through the powder line on the basis of the pressure detected by the pressure sensor in the powder line, the offset pressure value and a correction value.

Abstract: A pressure regulator for a fuel supply unit on a motor vehicle. A membrane is connected to an annular element of a housing and a moving piston by a laser welding technique. A reliable sealing of the membrane is thus guaranteed even at temperatures below 0° C. The region above the piston is thus reliably separated from the region below the piston.

Abstract: Disclosed is a pressure regulator for a fuel supply unit of a motor vehicle comprising a valve for joining a connection to an outlet above a designated pressure in the connection, a valve body and a valve seat, and a spring element for prestressing the valve body against the valve seat, characterized in that the valve body is designed as a sheet-metal part.

Abstract: The invention relates to a pressure regulator for a fuel supply unit on a motor vehicle, whereby a membrane (11) is connected to an annular element (3) of the housing (1) and a moving piston (2) by a laser welding technique. A reliable sealing of the membrane (11) is thus guaranteed even at temperatures below 0° C. The region above the piston (2) is thus reliably separated from the region below the piston (2).

Abstract: A suction jet nozzle and a diffuser having an inflow cone with an elliptical cross-section is implemented in a suction jet pump to be used in a motor vehicle's fuel tank. The jet nozzle is configured to produce a flat propulsion jet that seals the diffuser over its entire circumference.
