摘要： A rotary valve comprises a bushing and a cylindrical spool rotatably received by the bushing. The rotary valve avoids redundant control edge pairs by having exactly one first supply edge pair (P-C1) for controlling a first fluid supply path, exactly one second supply edge pair (P-C2) for controlling a second fluid supply path, exactly one first return edge pair (C2-R1) for controlling a first fluid return path, and exactly one second return edge pair (C1-R2) for controlling a second fluid return path. A first angle between the first supply edge pair and the first return edge pair, and a second angle between the second supply edge pair and the second return edge pair, are each greater than or equal to 120 degrees and less than 180 degrees. Geometric simplicity is achieved by tolerating a limited degree of force imbalance in valve operation.

摘要： A liquid flow rate control valve is provided in which since a total area of overlapping sections of a communication hole group (38c, 38d) of a distributor (38) and an outlet opening (37a, 37b) of a sleeve (37) changes when the distributor (38) is rotated by a first electric motor (46), if a rotor (42) is rotated by means of a second electric motor (47), an input port (31e) communicates with an output port (31f) through an inlet opening (42c, 42d) of the rotor (42), the communication hole group (38c, 38d) of the distributor (38), and the outlet opening (37a, 37b) of the sleeve (37) when the inlet opening (42c, 42d) of the rotor (42) passes through the overlapping sections, thereby making it possible to carry out PWM control of a flow rate of liquid. Since a thrust load in an axis (L) direction does not act on the distributor (38) and the rotor (42), supporting the distributor (38) and the rotor (42) becomes easy, thereby enabling the cost and weight to be cut.

摘要： A liquid flow rate control valve is provided in which since a distributor (38) is rotated relative to a sleeve (37) by a first drive source (46) only through a predetermined angle, the total area of overlapping sections of a first opening (37a) of the sleeve (37) and the second opening (38c) of the distributor (38) changes, and a rotor (42) having a third opening (42c 42d) is rotated by a second drive source (47), it is possible to carry out PWM control of the liquid input from an input port (61e) and output it from an output port (61f). In this process, one end in an axis (L) direction of the rotor (42) disposed on an inside in a radial direction is coaxially connected to the second drive source (47), and one end in the axis (L) direction of the distributor (38) disposed on an outside in a radial direction is connected to the first drive source (46) via a gear train (66, 73, 70), and therefore, it is possible to individually rotate the distributor (38) and the rotor (42) while achieving a compact size by arranging the first and second drive sources (46, 47) in a concentrated manner at one end in the axis (L) direction of a liquid flow rate control valve (23).

摘要： In one aspect of the present invention, a system for a downhole string comprises a fluid path defined by a bore formed within a tubular component. A reciprocating valve is located within a wall of the bore hydraulically connecting the bore with a fluid passage. The valve comprises a substantially cylindrical shaped housing. First and second ports are disposed on a circumference of the housing, and a fluid pathway is disposed intermediate the first and second ports. The valve comprises an axially slidable spool disposed within and coaxial with the housing and comprises a blocker. The blocker is configured to slide axially so to block and unblock the fluid pathway to control a flow from the bore to the fluid passage. The valve comprises a plurality of seals. Each seal is disposed opposite of the blocker causing pressure to be equally applied to the blocker and the plurality of seals.
