Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
166 words
A combination fuel pressure regulator and fuel injector which comprises: a housing comprising a cylindrical sidewall and having a hollow interior divided into a fuel chamber and a control chamber by a pressure regulating diaphragm that carries a valve element; an inlet via which pressurized fuel is delivered to the fuel chamber; a valve seat disposed within the fuel chamber for coaction with the diaphragm-carried valve element and leading to an outlet via which excess fuel is returned from the fuel chamber to tank; a spring that biases the diaphragm and valve element toward the valve seat for establishing the regulation pressure; an injector-receiving socket disposed directly on the cylindrical sidewall of the housing in direct fluid communication with the fuel chamber; and an electromechanical fuel injector having an inlet received in the socket in a fluid-tight manner and receiving pressurized fuel from the fuel chamber; and in which said socket is a separate element that is joined with said cylindrical sidewall in a fluid-tight manner.
Claim 2
Dependent Claim

Claim 4
Dependent Claim
202 words
A combination fuel pressure regulator and fuel injector which comprises: a housing comprising a cylindrical sidewall and having a hollow interior divided into a fuel chamber and a control chamber by a pressure regulating diaphragm that carries a valve element; an inlet via which pressurized fuel is delivered to the fuel chamber; a valve seat disposed within the fuel chamber for coaction with the diaphragm-carried valve element and leading to an outlet via which excess fuel is returned from the fuel chamber to tank; a spring that biases the diaphragm and valve element toward the valve seat for establishing the regulation pressure; an injector-receiving socket disposed directly on the cylindrical sidewall of the housing in direct fluid communication with the fuel chamber; and an electromechanical fuel injector having an inlet received in the socket in a fluid=tight manner and receiving pressurized fuel from the fuel chamber; and including a second injector-receiving socket disposed directly on the cylindrical sidewall of the housing in direct fluid communication with the fuel chamber and spaced circumferentially of the first-mentioned socket; and a second electromechanical fuel injector having an inlet received in said second socket in a fluid-tight manner and receiving pressurized fuel from the fuel chamber.
Claim 5
Dependent Claim
