HYDRAULIC SYSTEM Russian patent published in 2010 - IPC F15B21/04 

FIELD: machine building.

SUBSTANCE: invention refers to machine engineering of hydraulics and can be used in hydraulic systems of transport facilities operating in open air. Contacts out of heat-resistant material are oppositely to each other arranged on an external wall of a tank opposite to a suction branch with a diffuser and on the external part of the case of a jet pipe. The suction branch with the diffuser has double walls. A heater of working agent is installed between these walls. The heater is connected with one of the heat-resistant contacts located on the external wall of the tank and via a current generator - with another heat resistant contact located on the external part of the jet pump case.

EFFECT: increased operability of hydro-system due to reduced time of reaching optimal heat mode of working agent.
