Thermostat valve for a combustion engine

Thermostat valve for a combustion engine, comprising a housing, which comprises several cooling fluid connections and comprising at least one first hollow valve element, which has a spherical or spherical-segment shaped shell surface and is mounted rotatably in the housing, wherein the at least one first valve element comprises several openings limited by the shell surface, which openings can be selectively connected with one or several of the cooling fluid connections of the housing by rotation of the at least one first valve element,

• wherein at least one second valve element is provided which is rotatable in the housing relative to the at least one first valve element, wherein the at least one second valve element can selectively close or open one or several of the cooling fluid connections of the housing through rotation, and wherein a rotational drive is provided, with which the at least one first valve element and/or the at least one second valve element can be driven rotatably, and
• wherein the at least one second valve element is arranged rotatably mounted in the housing beside the at least one first valve element, wherein the at least one first and the at least one second valve element in each case have an axial opening on their sides facing towards each other, wherein the axial openings communicate with one another.
