专利汇可以提供A fluid injector and pressure amplifier专利检索,专利查询,专利分析的服务。并且A hydraulically operated fuel injector for compression-ignition engines which includes an electronically or pneumatically operated hydraulic pilot-control valve (30) which is supplied with fuel under substantially constant pressure from a pump driven directly or indirectly by the engine. The pilot-control valve (30) is connected by supply and exhaust passages to a slave valve which in turn controls the admission of fuel to a charging cavity (86) located adjacent to an outlet valve (98) to the combustion chamber. The slave valve is a stepped diameter piston (72 and 82) which functions as a pressure amplifier for the fuel supply to the combustion chamber. Fuel from the pump which is received at relatively low pressure through the slave valve is amplified to high pressures sufficient to overcome compression and combustion pressures of the engine and the resistance of spring seated injector outlets and/or the fuel supply orifice(s).,下面是A fluid injector and pressure amplifier专利的具体信息内容。
