Hydraulic tensioning device for combustion engine incorporates piston, pressurized oil chamber, return valve, leakage gaps, compression spring, displacer body and support flange |
摘要 |
A piston (4) is movably slides along a sleeve-type holder (2) which, together with the piston, forms a pressurized oil chamber (3) supplied with oil by means of a return valve (5). A compression spring (6) exerts pressure on the piston. A first leakage gap (7) is between the piston and holder. A further leakage gap (8) is between the pressurized-chamber side of the inner wall (9) of the piston and a cylindrical insert (10). Any excess oil pressure in the pressurized oil chamber is reduced by a valve (12) with discharge opening (11). The insert is in the form of a support-flange (14) located in the displacer (13) in the piston-spring, with a compression spring thrust piece (15). The support flange joined to the displacer contain a graduated hole (16) for a piston-valve (17), with pressure-die (18) and pressure-control-groove (19).
