摘要： A rotational control apparatus (A) having a rotatable input (26 or 180) and output (26 or 180) with respective interface discs (106, 180). Three sets of two diametrically opposed pistons (64 and 66, 68 and 70, 72 and 74) are controllable to rotatably relate the interface discs (106, 180). The piston sets (64 and 66, 68 and 70, 72 and 74) include piston heads (76) with dissimilar diameters such that each of the sets of pistons (64 and 66, 68 and 70, 72 and 74) may apply a dissimilar torque for a given amount of air pressure. Each of the piston sets (64 and 66, 68 and 70, 72 and 74) may be actuated independently or in combination with each of the other sets of pistons (64 and 66, 68 and 70, 72 and 74) such that the interface discs (106, 180) may be rotatably related to each other with varying degrees of torque. The rotational control apparatus (A) also includes a unique interface disc (106) with a frustoconical annular projection (136) for drawing relatively hot air away from the hub (26) near the interface disc (106) and out of the apparatus (A). The rotational control apparatus (A) further includes a unique set of axially extending channels (38, 60, 111) for the conveyance of air for cooling the interface discs (106, 180) from a location remote from the interface discs (106, 180). Blades (152) on interface disc (106) draw relatively cool air through the channels (38, 60, 111) to the hub (26) near the interface disc (106).

摘要： A rotary fluid displacement apparatus (100) with an orbiting toothed ring member (30) is shown with an improved casing (60) and rolling support between the faces of the valve discs (46, 47) and the first and second fluid transfer elements (21, 35). Particularly, needle bearings (106, 112) are sandwiched between thrust washers (108,114) and then between the valve discs (46, 47) and the fluid transfer elements (21, 35), with one of the needle bearings (106) being piloted in an annular groove (110) formed in the annular plate (23) of the first fluid transfer element (21) and the other of the needle bearings (112) being piloted on the hub (35') of the second fluid transfer element (35). The casing (60) includes two pieces, i.e. a generally cylindrical portion (62) and an end cap (64). The portion (62) includes four cavities (70, 72, 74, 76), with the hub (35') of the second fluid transfer element (35) being in a sliding rotatable, and sealing relation with the axially inner cavity (76) and the end cap (64) being in sliding and sealing relation with the axially outer cavity (70). The end cap (64) includes a cavity (90) for slideably, rotatably, and sealing receipt of the hub (24) of the first fluid transfer element (21). Fluid communication is allowed axially through the end cap (64) by an axially extending fluid conduit (94) intersecting with the cavity (90) of the end cap (64) and by an axially extending fluid port (98) which intersects with first and second axially extending fluid bores (82, 96) formed in the generally cylindrical portion (62) and the end cap (64) which in turn intersects with a radially extending fluid conduit (80) terminating in the axially inner cavity (76).

摘要： A hydraulic spool valve assembly includes a pair of lands spaced apart by a groove, one land comprising a piston face, an adjacent land comprising a hydraulic flow notch, wherein the piston face includes a pair of concentric radially concave concentric. The boundary between the two concave annuli defines a convex split point annulus. The notch is oriented so as to establish a hydraulic fluid flow adapted to impact the split point annulus so as to create inversely directed radial flows across the respective concave annuli. A reverse flow component is thereby established across the groove and back toward the notch to lessen the impact of the force of the hydraulic stream against the split point annulus.
