摘要： A variable valve actuation (VVA) apparatus comprises a supporting arm to support a pivot center of a rocker arm. The rocker arm operates a valve operating (VO) cam in response to operation of a drive cam on an engine driven drive shaft. The supporting arm is mounted for angular motion about an axis of rotation of the drive shaft to move the pivot center of the rocker arm along a circle about the drive shaft axis. The VO cam is mounted for pivot motion about the drive shaft axis. A supporting arm (SA) actuator is provided to position the pivot center of the rocker arm to any angular position to shift mode of operation of the VVA apparatus.

摘要： A variable valve actuation apparatus incorporates a mechanism, mounted to a control shaft, to convert rotational motion of a camshaft into pivotal motion of a valve operating cam. The mechanism has different states corresponding to varying angular positions which the control shaft is adjustable to, respectively, The mechanism is continuously variable in state to one of the different states in response to a shift of the control shaft to one of the varying angular positions. The mechanism is also operative to vary the valve operating cam, in position, relative to the associated cylinder valve in response to a shift between the different states.

摘要： A removably supporting mechanism is provided for a workpiece holding device that can hold and release a workpiece. The workpiece holding device is removably supported on a crossbar extending substantially orthogonal to a workpiece conveying direction of a press machine. The removably supporting mechanism has a guide pin and a guide pin hole. The guide pin is fittable into and engageable with the guide pin hole. One of the guide pin and the guide pin hole is disposed on the workpiece holding device side, whereas another of the guide pin and the guide pin hole is disposed on the crossbar side. The guide pin and the guide pin hole can perform alignment of the workpiece holding device and the crossbar in a direction substantially orthogonal to an inserting direction of the guide pin.

摘要： A breakage prevention mechanism includes a pair of arms which is synchronized and moves approximately parallel, and a crossbar bridged between the top end of the arms. Both end of the crossbar and the arm are connected pivotably around two axis. Both end of the crossbar are configured to be slidable against the arm in X axis direction. A plunger is placed between both end of the crossbar and arm, which protects the crossbar by restraining the pivoting and the sliding of both in the normal condition and releasing the restraint when the unintended force is given.
