    摘要: A continuously operable fuel injection device comprises a sleeve having a substantially triangular measuring window communicating with the outlet port of a main body, the sleeve being inserted in the cavity of the main body, and a control spool having an annular groove communicating with the inlet port of the main body through an axially extending hole and axially slidably inserted in the sleeve, the substantially triangular measuring window cooperating with the annular groove of the control sleeve to form a variable orifice. By axially sliding the control spool, any desired flow rate can be obtained.
