Abstract

936,316. Hydraulic transmissions. BERGENS MEKANISKE VERKSTEDER A.S. March 13, 1961 [March 16, 1960], No. 9073/61. Class 69 (2). [Also in Group XXX] An hydraulically driven mooring winch 10 normally powered from a main pump 1 driven by an electric motor 3 is provided with a low capacity auxiliary pump 11 driven by an auxiliary low power electric motor 12 for use in maintaining the ropes taut during tidal movements &c. whilst releasing the main pump 1 for other purposes. The capacity of the auxiliary pump may be variable. A regulating valve 8 maintains a constant pressure in the supply line and thereby maintains a constant pull on the ropes. The auxiliary electric motor 12 is controlled from a pressure-sensitive switch 13 which operates to drive the pump 11 at high speed when the pressure in the system drops so that slack in the ropes is taken up rapidly. A rise in pressure due to tightening of the ropes causes the motor 12 to reduce speed and thereby reduce the power loss at the regulating valve 8.
