The invention is related to mechanical engineering and can be used in fluid power systems for transfer of fluid power between working fluids with different temperatures at reduced heat exchange between them. The objective of the present invention is creation of a hydraulic buffer for fluid power transfer between working fluids with different temperatures at reduced heat exchange between them. The objective is achieved by the proposed hydraulic buffer (hereinafter—the buffer) comprising a housing with at least two variable-volume reservoirs separated from one another, each of them communicating with its port in the housing. The variable-volume reservoirs are separated from one another by at least two separators with at least one buffer reservoir made between them filled with working fluid preferably with low heat conductivity, i.e. not exceeding 0.2 W/m/K.
A hydraulic buffer comprising a housing with at least two variable-volume liquid reservoirs in it separated from one another, each of them communicating with its port in the housing, wherein said variable-volume liquid reservoirs are separated from one another by at least two separators with at least one liquid buffer reservoir made between them and at least in one buffer reservoir means of convection suppression are made.
A hydraulic buffer comprising a housing with at least two variable-volume liquid reservoirs in it separated from one another, each of them communicating with its port in the housing, wherein said variable-volume liquid reservoirs are separated from one another by at least two separators with at least one liquid buffer reservoir made between them, wherein said separators are made elastic, wherein at least one of said separators is made from a material capable of being used at a temperature of 200° C. and higher.
A hydraulic buffer comprising a housing with at least two variable-volume liquid reservoirs in it separated from one another, each of them communicating with its port in the housing, wherein said variable-volume liquid reservoirs are separated from one another by at least two separators with at least one liquid buffer reservoir made between them, wherein the housing includes at least one heat-insulating element made so as its heat conductivity at least in one direction does not exceed 20 W/m/K while said heat-insulating element forms the external walls of at least one liquid buffer reservoir.
