Claim Text:
1. A thermostatic cartridge for regulating hot and cold fluids to be mixed, comprising: a casing that is hollow, defines an axis and delimits an outlet for a mixture of the hot and cold fluids, a slide valve for regulating the temperature of the mixture, which: a thermostatic element that comprises a piston, connected to the casing, and a body secured to the slide valve, the piston and the body being able to move with respect to each other substantially along the axis under the action of an expansion of a heat-expandable material contained in the body along a thermosensitive part from which the mixture flows downstream from the slide valve, wherein the slide valve delimits externally: a hot channelling groove for channelling the hot fluid, which is adapted to distribute the hot fluid supplying the hot-fluid inlet over the entire external periphery of the slide valve and defines a hot free space for circulating the hot fluid around the slide valve, the hot free space being equal to or greater than the maximum volume of fluid that is permitted in service by the hot fluid inlet, and a cold channelling groove for channelling the cold fluid, which is adapted to distribute the cold fluid supplying the cold fluid inlet over the entire external periphery of the slide valve and defines a cold free space for circulating the cold fluid around the slide valve, the cold free space being equal to or greater than the maximum volume of fluid that is permissible in service through the cold fluid inlet.
