#CMT# #/CMT# The valve (1) has a rotary valve housing (2) with a cross-section adjusting link part (3) i.e. hollow sphere (3a). The housing comprises housing flow openings (4, 5) with valve seats (6, 7). The openings form a flow path for fluid by rotation of the link part in variable intersection with a rotary valve flow opening (8) to form the flow path for fluid. The link part more displaceably forms another flow path from the valve seats along a rotational axis (A) by a temperature-dependent element (11) i.e. expansion material element, after exceeding swelling temperature of the fluid. #CMT#USE : #/CMT# Fail safe rotary valve for engine construction for regulating and distributing coolant flow in a refrigerant circuit of an internal combustion engine. #CMT#ADVANTAGE : #/CMT# The valve can be secured against failure in a simple and reliable manner and with small installation spaces. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a cross-sectional view of a rotary valve.
