A hydraulic automatic tensioner for adjusting the tension of a bell includes a first member with a piston formed integrally, a second member combined with the first member and axially movable relative to the first member, a cylinder formed integrally with the second member, together defining a fluid-reservoir chamber for hydraulic fluid, axially slidably receiving the piston, and a spring pushing the members apart. The piston and cylinder form a pressure chamber filled with hydraulic fluid. The second member has a leak passage through which fluid flows from the pressure chamber into the fluid-reservoir chamber. A control valve is placed in the leak passage, inhibiting flow of fluid from the pressure chamber into the fluid-reservoir chamber. A control device moves the control valve to close the leak passage when activated and makes it ineffective when deactivated so that the pressure chamber communicates with the fluid-reservoir chamber via the leak passage.

Hydraulic automatic tensioner and power transmitting mechanism

The present invention is made to operate auxiliary machine while an engine is stopped, to start an engine and to charge a battery by providing a single motor and a simple construction and by providing a simple control operation. An engine system comprises an engine, a motor, and auxiliary machine, and further comprises a planetary mechanism having three elements comprising a sun gear, a carrier and a ring gear, to which any one of an output shaft of the engine, an output shaft of the motor and a drive shaft of the auxiliary machine are respectively connected, a uniting connection device capable of uniting two or more elements of the planetary mechanism, and a rotation direction restriction device which restricts a rotation direction of the drive shaft of the auxiliary machine to one direction.
