Abstract: According to one aspect, a rotary exhaust valve system includes an arcuate ring having a first plurality of apertures and a rotary valve ring disposed in an overlapping relation with the arcuate ring. The rotary valve ring has a second plurality of apertures forming therein corresponding to at least some of the first plurality of apertures. A first crank is disposed in a first side of the rotary exhaust valve system, and a second crank is disposed in a second side of the rotary exhaust valve system. The second crank is connected to the first crank and the rotary valve ring, and the first crank actuates the second crank and moves the rotary valve ring such that openings of the first plurality of apertures are closed and opened.

Abstract: A seal assembly and method of directing fluid flow away from a seal. The seal assembly comprises an inner seal member coupled to a rotatable shaft and an outer seal member which is either rotatable or static. The inner seal member has a plurality of knives spaced apart from each other and extending radially away from the shaft. The outer seal member has a rub surface disposed to abut a terminal edge of at least one of the plurality of knives to thereby form a seal. An outer knife of the plurality of knives of the inner seal member extends axially at an angle and is adapted to direct fluid flow away from the seal.
