Title:
【発明の名称】燃料噴射ポンプの圧力ビルドアップ一時的中断装置
Document Type and Number:
Japanese Patent JPH0646020
Kind Code:
B2
Abstract:
Devices for dividing the process of fuel injection into two phases, i.e., pre-injection and main injection, with a pressure relief body opening up an expansion space when the fuel injection pump has reached a given level of pressure, are known to be provided with a by-pass line which can shut off by a spring-loaded slide valve. A simpler design of such a pressure relief system is achieved by having the by-pass line lead from the expansion space to a by-pass opening which is located in the cylinder wall of the pressure chamber of the pump and is intermittently covered by the pump plunger, and by making this opening cooperate with control edges on the pump plunger, leaving it uncovered in the injection-free state.
