Vacuum booster |
| abstract |
In a vacuum booster a vacuum passage (14) formed in a valve body (7) to provide communication between a control valve and a constant pressure chamber is furnished with a groove (14a) formed by a forming die used for moulding the valve body (7). …<??>The groove (14a) increases the sectional area of the vacuum passage (14) so that the air in the variable pressure chamber flows in a larger quantity toward the constant pressure chamber, to enable a quicker return to the rest position following a power stroke. …<IMAGE>… |
