Abstract: The invention is an inlet device or snow valve adapted to fit an air cleaner housing for a motor vehicle. The inlet device has an annular door with an open window that rotates between first and second positions. In the first position, the window of the annular door aligns with an outside air opening in the housing to allow the flow of outside air into the air cleaner apparatus. In the second position, the annular door rotates so the sidewall of the annular door covers the outside air opening and blocks the flow of outside air into the air cleaner apparatus. The second position allows the flow of under hood air into the air cleaner apparatus. In either position, the device preferably totally closes the other opening to assure all under hood intake air flow comes from the desired location.

Abstract: A screw press apparatus has frames, a screw shaft, an outside tube, a cylindrical screen, a screw blade, a supply pipe, and a cleaning pipe . Raw liquid is fed from the supply pipe via an opening of the screw shaft to the upstream region of the cylindrical space. The cleaning pipe ejects cleaning water onto the screen. Raw liquid fed from the opening to the upstream region is pressurized and carried towards the downstream region by the screw blade, and is separated into filtrate which flows through the fine holes out of the screen and a cake which moves in the cylindrical space, to be discharged from the downstream region. Sizes of the fine holes of the screen decrease gradually from the upstream region towards the downstream region.
