摘要： A spool valve includes: a housing including a spool hole; a spool inserted into the spool hole of the housing so as to be movable in an axial direction; a screw shaft arranged coaxially with the spool; an electric motor configured to rotate the screw shaft; a nut threadedly engaged with the screw shaft and configured to move in the axial direction when the screw shaft is rotated; a coupler through which the nut and the spool are coupled to each other; and a coil spring configured to apply biasing force to the spool, the biasing force acting so as to maintain the spool at a neutral position, the coil spring being arranged so as to overlap the nut when viewed from a radial direction of the screw shaft.

摘要： A fuel injector includes: a pilot fuel injection portion including a pilot fuel supply block and a pilot shroud; a main fuel injection portion arranged so as to surround the pilot fuel injection portion from an outer side in a radial direction; and an intermediate air passage arranged between the pilot fuel injection portion and the main fuel injection portion. The pilot shroud includes: a throat located at a downstream side of the pilot fuel supply block; and a flame holding portion surrounding flame located at the downstream side of the throat. An air injection slit is formed at the flame holding portion, the air injection slit being configured to inject compressed air of the intermediate air passage in a direction along an inner peripheral surface of the flame holding portion such that the compressed air covers the inner peripheral surface over an entire periphery.
