Abstract
A chain tensioner, includes a housing intended for attachment to a stationary machine element of an internal combustion engine, and a piston received in the housing for axial displacement against a strand of a chain to thereby implement a tensioning of the chain. An adjusting mechanism is provided for moving the housing relative to the machine element in a direction to and away from the strand of the chain, whereby a spacer establishes a distance between the housing and the strand to thereby define an installation position of the housing.

A chain tensioner, comprising:
- a housing intended for attachment to a stationary machine element of an internal combustion engine;
- a piston received in the housing for axial displacement against a strand of a chain to thereby implement a tensioning of the chain;
- an adjusting mechanism for moving the housing relative to the machine element in a direction to and away from the chain strand;
- a spacer for establishing a distance between the housing and the chain strand to thereby define an installation position of the housing;
- and
- a transport safety mechanism for maintaining the piston in a transport position, wherein the transport safety mechanism has a retainer arm which forms the spacer and embraces an end portion of the piston.

A chain tensioner, comprising:
- a housing intended for attachment to a stationary machine element of an internal combustion engine;
- a piston movably received in the housing for tensioning a power transmission member of a drive;
- an adjusting mechanism for moving the housing in a direction to and away from the power transmission member;
- position-control means for establishing a predetermined distance between the piston and the power transmission member to thereby define an operating stroke of the piston;
- and
- a transport safety mechanism for maintaining the piston in a transport position, wherein the transport safety mechanism has a retainer arm which forms a spacer and embraces an end portion of the piston.
