DEVICE FOR CHANGING DIRECTION OF COOLANT FLOW AND DIVIDING IT Russian patent published in 1995 - IPC

Abstract RU 2047803 C1

FIELD: hardening and thermomechanical treatment of articles. SUBSTANCE: change-over member made in form of hermetic chamber is rotatably mounted in housing provided with inlet and outlet branch pipes. Interior of hermetic chamber is connected with pressure source. Secured on wall of member is central sector made of flexible material; area of this sector exceeds passage area of outlet branch pipe. There are several holes in the wall. Rigid sectors made in form of wings with cuts are provided over edges of member. Clearance is formed between outer surface of central sector facing the outlet branch pipe and inner surface of housing. EFFECT: enhanced reliability. 4 dwg
