Abstract
A driver that reciprocates has its reciprocation divided into a non-actuating portion and an actuating portion. The driver in one embodiment positions a carrier that has two pins, each pin being slidably mounted in its slot on a housing. One of the pins is an output pin that may be linked to operatively position a valve of an internal combustion engine. The two slots are configured such that each pin, during its motion range, does effect a capture of the other pin such that the captured pin is generally stationary. When the output pin is captured, the driver reciprocation causes the non-output pin to perform a lost-motion traverse of its slot. When the non-output pin is captured, the driver reciprocation actuates the output pin. A linked pair of such embodiments driven by a single driver can thus alternately actuate two valves.
