Combined fuel pressure regulator and fuel injector device
This patent describes a combination fuel pressure regulator and fuel injector. It 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; 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 the socket is a separate element that is joined with the cylindrical sidewall in a fluid-tight manner.
