摘要： A chain tensioner is provided which is configured such that the air remaining in a pressure chamber can be discharged to the outside through a helical gap defined between a screw and a threaded hole, and through between circumferentially separate radial ends of a spring washer mounted between the screw and a housing. The chain tensioner includes an air discharge groove or grooves formed in the seat surface of the head of the screw such that an annular space defined between the neck of the screw and the inner diameter surface of the spring washer communicates with the outside through the air discharge groove or grooves. Even if foreign objects clog the space between the separate radial ends so as to hinder air from being discharged through between the separate radial ends, the air remaining in the pressure chamber can be discharged to the outside through the air discharge groove or grooves.

摘要： Deaeration of the high pressure oil chamber of a hydraulic tensioner takes place though a helical orifice formed by opposed flanks of the threads of a threaded hole in the tensioner housing and the threads of a screw inserted into the hole. The opposed flanks are maintained in spaced relationship by a force exerted by a spring washer disposed between the head of the screw and a surface of the tensioner housing surrounding the opening of the threaded hole. The flank of the thread of the hole that forms part of the boundary of the helical orifice can have a concave curvature in order to increase the aperture of the air flow path. A groove in the surface surrounding the opening of the threaded hole prevents the washer from sealing off the flow of air. This groove is disposed with its exit end at a level above its entry end.

摘要： An air bleeding valve includes an annular valve element for removing air from oil contained in a hydraulic circuit of a hydraulic tensioner and for suppressing the removal of the oil. An air bleeding valve body is fitted in an air bleeding valve accommodating hole formed in the hydraulic tensioner. A circumferential groove having a rectangular cross section is formed on an outer circumferential surface of the air bleeding valve body. The annular valve element having a rectangular cross section is fitted in the circumferential groove so as to be movable in an axial direction parallel to the axis of the annular valve element, and displaceable in a radial direction toward and away from the axis of the annular valve element. Such air bleeding valve removes air in a hydraulic circuit while suppressing the removal of oil in the hydraulic circuit during starting operation of an engine.
