Abstract: A cooling module includes a pump that pumps fluid, and a manifold including inside at least one fluid channel through which the fluid flows, in which the manifold includes a discharge portion from which the fluid from the pump is discharged, a channel connection chamber connected to upstream of the fluid channel in a direction in which the fluid flows, and a communication channel allowing the discharge portion and the channel connection chamber to communicate with each other.

Abstract: A valve timing controller includes: a driving side rotation member synchronously rotating with a crankshaft of an internal combustion engine; a driven side rotation member disposed coaxially with a rotary shaft center of the driving side rotation member and rotating integrally with a valve opening/closing cam shaft; advancing and retarding chambers formed between the driving side and driven side rotation members; a valve unit disposed coaxially with the rotary shaft center and controlling feeding and discharging of a fluid to and from the advancing and retarding chambers; and a tubular valve case having an internal space extending in a direction along the rotary shaft center, accommodating the valve unit in the internal space, having an opening at one end in the direction along the rotary shaft center, and having a bottom portion at the other end.

Abstract: A valve opening/closing timing control device includes: a driving side rotator synchronously rotating with a crankshaft of an internal combustion engine; a driven side rotator coaxially disposed with a rotation axis of the driving side rotator and integrally rotating with a valve opening/closing camshaft; advance and retard chambers formed between the driving side and driven side rotators; a lock mechanism including a lock member capable of engaging with a recessed portion on one of the driving side and driven side rotators and provided in the other of the driving side and driven side rotators; and a connecting bolt coaxially disposed with the rotation axis and connecting the driven side rotator to the camshaft. The connecting bolt includes an internal space, and an advance port, a retard port and a lock port are formed as through-holes, a valve unit accommodates a spool, and the spool includes an internal flow path.
