Hydraulic separator

Abstract

The invention relates to a hydraulic separator to be fitted between a primary liquid circuit and a secondary liquid circuit, in such a manner that the first and secondary liquid circuits are hydraulically independent. The hydraulic separator has an elongate body with an internal space which is delimited by a wall. In the internal space there is a feed port leading to the primary liquid circuit and a discharge port leading from the primary liquid circuit, which are located substantially on one longitudinal side of the hydraulic separator. Also in the internal space there is a feed port leading to the secondary liquid circuit and a discharge port leading from the secondary liquid circuit, which are located substantially on a different longitudinal side of the hydraulic separator. The feed port leading to the primary liquid circuit and the discharge port leading from the secondary liquid circuit are located substantially at a first height region of the hydraulic separator. The discharge port leading from the primary liquid circuit and the feed port leading to the secondary liquid circuit are located substantially at a different, second height region of the hydraulic separator. In the internal space of the hydraulic separator, both in the first height region and in the second height region, there is a set of open filler bodies which have a large surface area in relation to the volume which they take up.
