Abstract (en)
[origin: WO2021064065A1] The invention relates to a method for producing a rotary slide valve for regulating a flow of a fluid, comprising a rotary slide (02) which is rotatably mounted about a rotational axis (R) in a valve housing. The method has the steps of: producing the rotary slide (02) in an injection molding method, in particular in a plastic injection molding method; producing at least one circumferential or casing section (04) of the valve housing (03) in an injection molding method, in particular in a plastic injection molding method; and installing the rotary slide valve or a precursor thereof. According to the invention, a gap is formed between the rotary slide (02) and the directly adjacent valve housing circumferential or casing section (04) of the valve housing (03) in the radial direction, said gap allowing the rotary slide (02) to rotate about the rotational axis (R) and facilitating a seal which does not exceed a tolerable leak between the rotary slide (02) and the circumferential or casing section (04) of the valve housing (03).
