摘要： An eccentric rotary vane device useful either as an engine or a pump. The rotary device has a conventional main chamber, an inlet port and an outlet port communicating with the main chamber, a plurality of angularly related radial vanes, independently pivotable and rotatable about a vane axis within the main chamber. A rotor is eccentrically mounted with respect to the main chamber, and a power delivery shaft is connected with the rotor. Cylindrical vane guides in the form of a single roller or sets of two rollers engage the faces of adjacent vanes on either side so that the vane guides are maintained in substantially uniform engagement with the lateral faces of the vanes as they traverse radially inwardly and outwardly therealong during rotation of the rotor. The vanes have novel configurations on their lateral faces so that substantially a perfect seal is maintained between the vane guides and the lateral faces of the vanes when single rollers are employed as the vane guides and the number of vanes is odd. The invention also includes novel configurations of vane lateral faces for maintaining substantially perfect sealing between the vane guides and the lateral faces of the vanes when the vane guides include a carrier body with two spaced oppositely disposed rollers constituting a vane guide set and the number of vanes is odd or even, and when the vane guides each comprise a pair of mutually contacting rollers.

摘要： A cycle control device employing a parallel switching circuit to control a single or a predetermined number of cycles of a motor driven output shaft. A latching and a cycle switch in the parallel circuit are providing an overlapping switching sequence which is initiated by a latchable pushbutton and controlled further by the motor driven output shaft to the end of the cycle. An indexing arrangement is functioning to delay the unlatching and keeping the motor circuit energized until the unlatching and motor stopping can take place in a home position after a dial readable predetermined number of ratcheting steps have been completed. The control principle is applicable to a countdown version, a memory version with an automatic return or to a unit with a shaft mechanism to one or the other mode.
