Title: Throttle body
Inventor: HATADA NAOZUMI
IPC: B29C45/00
Filed: 2001-04-04
Abstract: PROBLEM TO BE SOLVED: To solve the conventional problems that a clearance between a bore of a throttle body and a throttle valve must be set to 80 to 100 μm or less, coefficients of linear expansion differ and thermal deformation amounts differ due to a difference in orientation of a filler with the bore even in resin having the same material when forming the throttle valve by resin, and roundness may worsen due to a difference in shrinkage after forming, thereby causing a possibility that the interference between the bore and the throttle valve and excessive clearance occur, to reduce weight and cost of the throttle body which is a part of an intake system using resin. SOLUTION: The orientation of the filler in resin is set in the circumferential direction to bring a coefficient of linear expansion in the radial direction close to the bore 4. For this reason, a groove 17 is concentrically arranged to set the orientation of the filler 2 in the circumferential direction. Moreover, an aggregate constituted by arranging the filler in the circumferential direction is heated and hardened after impregnating it with resin to obtain the throttle valve 1 in which the orientation of the filler is in the circumferential direction. Moreover, a rib 28 is arranged close to a position of a throttle valve stem to control a forming shrinkage amount and make roundness of the bore 4 small.
