摘要： The pressure reduction valve includes: a cylindrical portion, a piston and a spring. The cylindrical portion includes an inlet communicating with the primary side flow path and an outlet communicating with the secondary side flow path. The piston fitted into the cylindrical portion is slidable along an axis direction of the cylindrical portion within the cylindrical portion, and defines, within the cylindrical portion, a space communicating with the inlet and the outlet. The spring applies, to the piston, a force acting toward the space. The outlet is displaced in one direction from the center of the piston when seen in the axis direction. The force applied to the piston by the spring is distributed so as to deviate from the center of the piston to the side of the outlet.

摘要： The present invention provides a steel material for automobile chassis parts which has high fatigue characteristics, does not require much cost for heat treatment, and further is superior in shapeability and a method of production of automobile chassis parts using this steel material, that is, one being a steel material to which Nb and Mo have been compositely added and having a difference 50 to 150 points between a Vicker's hardness of the center of plate thickness and a maximum value of Vicker's hardness within 0.5 mm from the surface after bending by a bending R of the plate outer surface of 2 to 5 times the plate thickness. The surface is high in hardness and the center part is low in hardness, so the fatigue characteristics and shapeability are superior. Note that if annealing under conditions giving a tempering parameter » defined by »=T(20+log(t)) of 14000 to 19000 (where T is the absolute temperature, t is the time (h), and the temperature rise is 660°C), it is possible to relieve the internal stress and further improve the fatigue characteristics.
