ABSTRACT:
A rotary control valve for expansion fluid driven engines comprises a housing having inlet and outlet ports, a distribution port positioned at one end of the housing and communicating with the engine cylinder, and a first sealing face disposed about the distribution port. A rotor is mounted in the housing on a drive shaft, rotates therewith, and is capable of translating axially thereon. The rotor includes pressure and exhaust passageways which alternately communicate with the distribution port to pressurize and exhaust the engine cylinder. A second sealing face is positioned on the rotor about one end of the pressure and exhaust passageways, and mates with the housing sealing face to form a sliding seal therebetween. A seal ring is positioned between the periphery of the rotor and the housing, and divides the cavity defined therebetween into separate intake and exhaust chambers which respectively communicate with the intake and exhaust ports. The housing and rotor sealing faces are disposed within the exhaust chamber, such that operational fluid pressure urges the sealing faces abuttingly together with automatically varying compression, and forms a secure sliding seal sequentially between the distribution port and the pressure and exhaust passageways for efficient engine operation.
