Combustion engine cooling circuit controller has angular positions of feed, short circuit, radiator openings enabling closing position for both feed openings as well as opening positions

摘要

The controller has a control device rotatably mounted in a valve housing, two feed openings in the housing wall for cooling water sub-flows from both cylinder banks, an opening for a short circuit through both cylinder banks and an opening for a cooling water circuit to the radiator. The feed, short circuit and radiator opening positions are selected to achieve a closing position for both feed openings as well as various opening positions. The controller has a control device with through openings and blocking walls rotatably mounted in a valve housing, two feed openings in the valve housing peripheral wall for cooling water partial flows from both cylinder banks (2,3), a short circuit opening in the valve housing's peripheral wall for a short circuit through both cylinder banks and a radiator opening in the valve housing's peripheral wall for a cooling water circuit to the radiator (6). The angular positions of the feed openings, short circuit opening and radiator opening are selected to achieve a closing position for both feed openings in addition to various opening positions.
