of first bore 20 first o ring 80 provides an interference fit between actuator 14 and circumferential wall 24 of bore 20 creating a seal therebetween second o ring 82 provides an interference fit between actuator 14 and bore 20 when the actuator 14 is in the second position creating a seal therebetween to inhibit fluid flow from the fluid reservoir 16 to the working passageway 18 second o ring 82 is disengaged from bore 20 in the first position third o ring 84 provides an interference fit between actuator 14 and circumferential wall 36 of bore 20 when the actuator is in the first position creating a seal therebetween to inhibit fluid flow from the fluid reservoir 16 to the working passageway 18 third o ring 84 is disengaged from bore 20 in the second position turning now to fig5 collection chamber 66 is defined by the area between opposing radiused surfaces 86 88 of ribs 90 92 collection chamber 66 further includes an inner boundary defined by circumferential wall 94 and an outer boundary defined as circumferential wall 36 thus the volume of collection chamber 60 is the annulus defined by radiused surfaces 86 88 and circumferential walls 36 94 as presently preferred the volume of collection chamber 16 is approximately 0 001 in 3 or approximately the equivalent of one 1 drop of oil however one skilled in the art will recognize that the volume of collection chamber may be adjusted in accordance with the given application referencing fig1.
