摘要： There is provided a high pressure fuel pump which includes a reliable fuel seal having a long durability and which can be produced at a relatively low cost. When a rotating shaft 4 is rotated to rotate a swash plate 7, such rotation is transmitted to a piston shoe guide plate 8 through a thrust ball bearing 9. Since the plate 8 is supported by a spherical portion 16 of a rod 14 mounted to a body 12, the plate 8 performs a precession to recurrently operate a plurality of fuel pumps 21 to 25 disposed around the rod 14. Each of the fuel pumps 21 to 25 includes a bellows provided between an outer end of the piston and the body 12, and the bellows completely seals a fuel leaked from a sliding clearance between the piston and the cylinder. Since the leaked fuel is introduced into a return passage 19 through a groove formed in an outer wall of the cylinder, a large internal pressure is not applied to the bellows and therefore, the bellows can be made of a low-priced material such as Teflon.

摘要： A rocker shaft holder that supports a rocker shaft and a camshaft holder that supports an intake camshaft and an exhaust camshaft in association with the rocker shaft holder are superimposed and connected to each other on the upper surface of a cylinder head, and a fuel pump that supplies fuel at high pressure to an injector is driven by a journal on a shaft end of the exhaust camshaft. The fuel pump is fastened to the cylinder head by means of a bolt; to the integral type camshaft holder, in which a plurality of bearings are integrally connected together via connecting parts, by means of a bolt; and to the rocker shaft holder by means of bolts, and the rigidity of that parts on which the fuel pump is mounted is thereby enhanced to reliably support the camshaft and the rocker shaft.

摘要： An end plate of a fuel cell stack is directly fixed to a humidifier. A resin pipe is attached to an oxygen-containing gas outlet of an end plate through a resin coupling pipe. The resin pipe includes one end having a large diameter and the other end having a small diameter. The other end is provided at an off gas supply channel of the humidifier. The off gas supply channel includes an inclined channel. The other end extends up to an end of the inclined channel where inclination of the inclined channel is started. An off gas ejection port is formed at the other end. The off gas ejection port is opened to the end of the inclined channel where inclination is started. Condensed water returned along the inclined channel flows from the off gas ejection port into the resin pipe.
