Title:
高圧燃料供給ポンプ
Document Type and Number:
Japanese Patent JP6860598
Kind Code:
B2
Abstract:
To increase a valve-opening pressure at which a pressure relief valve is opened in order to deal with a higher pressure of the fuel, a large pressure relief valve is installed in a high-pressure fuel supply pump. This upsizes the high-pressure fuel supply pump. A pressure relief valve 104 is installed in a discharge joint 12. This can provide a high-pressure fuel supply pump that is not large too much and sufficiently performs a relief function by efficiently using the excessive space in the pump even when the fuel pressure is increased.
