Title:
FUEL SUPPLY DEVICE
Document Type and Number:
WIPO Patent Application WO/2005/075813
Kind Code:
A1
Abstract:
A fuel supply valve (1) has a fuel pressure regulating valve (11) received in a cylinder (31) such that a piston (32) is elastically urged by an elastically urging mechanism (33) toward a pressure receiving port (11A), where the fuel pressure regulating valve (11) is provided on the fuel exit side of a low pressure pump (3) to regulate a supply fuel pressure from the low pressure pump (3) to a predetermined pressure. A piston (32) responds to a fuel pressure applied to the pressure receiving port (11A) to open and close an overflow port (11B) provided in a side wall section of the cylinder (31), and thereby the pressure of fuel on the fuel exit side is regulated. A take-out port (11C) for taking out a lubricating fuel is provided at a position in the side wall section of the cylinder (31), the position being nearer to the pressure receiving port (11A) than the overflow port (11B), and the lubricating fuel is taken out prior to the start of pressure regulating operation.
