Abstract
The hydraulic tightener includes a body defining a cylindrical cavity, a piston slidably mounted in the cavity and a pressure-applying shoe for applying pressure against an endless connection such as a chain. Associated with the piston there is a high pressure chamber defined by part of the cavity and the piston, the high pressure chamber being connected to a source of hydraulic fluid under pressure through a check-valve. This high pressure chamber is fluidtight and has no orifice other than the orifice provided with the check-valve. The tightener also serves to lubricate the endless connection or chain by spraying the hydraulic fluid thereon.
