High-pressure pump for conveying fluid for accumulator injection system for internal combustion engines of motor vehicles, has low-pressure inlet and high-pressure outlet, where low-pressure inlet has valve

摘要

The high-pressure pump (10) has a low-pressure inlet (18) and a high-pressure outlet (22), where the low-pressure inlet has a valve (20), over which the fluid is supplied to a pump chamber (16). The pump chamber is formed in the pump housing (12). The fluid is derived from the pump chamber in a high-pressure fuel accumulator over the high-pressure outlet.
