FIELD: engines and pumps.

SUBSTANCE: liquid-propellant engine (LPE) chamber includes a mixing head, internal shaped cover on external surface of which there made are ribs of cooling circuit, external shaped cover installed on internal one and attached to it by means of soldering along tops of ribs of cooling circuit. Between ribs of cooling circuit there are hollow connection straps attaching tops of ribs to each other; at that, external profile of the above connection straps corresponds to profile of cooling circuit. In order to increase the cover stability, connection straps attach the tops of two adjacent ribs to each other, connection straps attach the tops of all ribs to each other so that common annular surface is formed, and the external profile of which is equally spaced relative to internal profile of external cover at point of contact with external surface of internal cover.
