Abstract

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).

Dependent claims

A liquid flow rate control valve in which

a cylindrical distributor (38) and a cylindrical rotor (42) are coaxially disposed on an axis (L) in an interior of a cylindrical sleeve (37) fixed to a valve housing (36),
rotating the distributor (38) only by a predetermined angle relative to the sleeve (37) by a first drive source (46) changes an area of an overlapping section in which a first opening (37a, 37b) formed in the sleeve (37) and a second opening (38c, 38d) formed in the distributor (38) overlap one another, and
rotating the rotor (42) at a predetermined speed relative to the sleeve (37) and the distributor (38) by a second drive source (47) generates a liquid pressure at a predetermined duty ratio by a third opening (42c, 42d), formed in the rotor (42), communicating with the first opening (37a, 37b) and the second opening (38c, 38d) when the third opening (42c, 42d) passes through the overlapping section,
wherein one end in the axis (L) direction of that one of the distributor (38) and the rotor (42) which is disposed on an inside in a radial direction is coaxially connected to one of the first and second drive sources (46, 47), and one end in the axis (L) direction of that one of the distributor (38) and the rotor (42) which is disposed on an outside in the radial direction is connected to the other one of the first and second drive sources (46, 47) via a gear train (68, 70, 73).
