A piston is set such as to partition an inner space of a plunger into an adjustment space on the front side and the oil pressure chamber on the rear side, a piston restricting member restricting the movement of the piston toward the adjustment space. An oil relief mechanism is configured to cause the piston to move forward when oil pressure in the oil pressure chamber rises so as to discharge oil inside the oil pressure chamber to the outside. The piston restricting member has an orifice function that can control the amount of discharged oil.

Tensioner

An object of the present invention is to provide a tensioner lever that can reduce vibration and noise when the chain runs, and realize smooth attachment into an engine with minimal deformation of the lever body with a simple configuration. A tensioner lever according to the present invention includes a lever body and a torsion coil spring pressed the lever body toward the chain. The lever body includes a stopper member mounting part where a stopper member by which the support arm of the torsion coil spring is locked and which retains the torsion coil spring in a compressed state is removably mounted. The stopper member mounting part is located closer to a distal end of the lever body than a center position in the longitudinal direction of the lever body, or a center of gravity position of the lever body.

Tensioner lever

An object of the present invention is to provide a tensioner that has a reduced number of components and weight, and is easy to assemble. The tensioner has a base member loosely fitted into an open rear end of a cylindrical plunger with a closed front end against the resiliency of a biasing means accommodated inside the plunger. The tensioner includes a plunger stopper mechanism configured such that an engaging part formed on the base member detachably engages an engaging groove provided on an inner circumferential surface of the plunger directly or via another member.

Provided is a tensioner capable of stabilizing an oil pressure in an oil pressurizing chamber. The tensioner includes a pressure adjustment unit. The pressure adjustment unit includes a unit case attached to the housing or the plunger, a moving member disposed in the case inner space to be capable of moving closer to and farther away from the oil pressurizing chamber, and a pressure adjustment biasing unit which biases the moving member toward the oil pressurizing chamber. A gap between an inner wall of the case inner space and the moving member is configured to be held in a liquid tight state at any position between a position where the moving member is closest to the oil pressurizing chamber as a result of moving and a position where the moving member is most distant from the oil pressurizing chamber.

An object of the present invention is to provide a tensioner that has a reduced number of components and lighter weight and is easy to assemble. The tensioner according to the present invention is configured such that a base member is detachably and mechanically joined to a rear end opening of a cylindrical plunger with a closed front end against the resilience of biasing means that is accommodated inside the plunger such as to be freely extend and contract. The joint between the plunger and the base member is a mechanical connection that is one of a thread engagement, a press-fit, and a pin connection.

A plasma treatment apparatus is provided to suppress plasma from being generated between an antenna conductor and a lid to prevent contamination inside a vacuum chamber and to put an elongated antenna unit to practical use. The plasma treatment apparatus includes a vacuum chamber that accommodates a treatment target; an inductively coupling antenna unit that generates plasma in the vacuum chamber; and a high frequency power source that supplies a high frequency power to the inductively coupling antenna unit. The inductively coupling antenna unit has one or a plurality of antenna conductors and a lid that covers an opening formed in a wall surface of the vacuum chamber, and the one or plurality of antenna conductors are attached to the lid without a gap where discharge may occur.

Plasma treatment apparatus and driving method thereof

To provide a tensioner capable of keeping oil pressure in an oil pressure chamber stable with a simple structure. The tensioner is equipped with a pressure adjusting mechanism that adjusts oil pressure in the oil pressure chamber and includes an adjustment space formed in a housing and communicating with the oil pressure chamber, a movable member disposed such as to be movable to and from the oil pressure chamber, and a pressure adjusting biasing unit that biases the movable member toward the oil pressure chamber. A liquid tight seal is maintained between the movable member and an inner wall of the adjustment space, between a position where the movable member has moved closest to the oil pressure chamber and a position where the movable member is farthest from the oil pressure chamber.

The present invention provides a chain tensioner that automatically adjusts flow path resistance inside an oil leak path with a simple configuration to make it possible to reduce a change in damping characteristics resulting from a change in oil temperature and reduce an increase in manufacturing cost. In the chain tensioner, a pressure oil chamber is provided with an oil leak path communicating with an outside of the chain tensioner, the oil leak path contains a movable piece which is movable with a temperature-dependent deformation member that deforms according to oil temperature, and the movable piece is formed into a shape that changes flow path resistance of the oil leak path according to a position to which the movable piece is moved.
