ABSTRACT:
A hydraulic fluid control valve (18) includes first and second valve members (60, 62) which are rotatable relative to each other about an axis (23). The valve members (60, 62) define hydraulic fluid flow orifices (110) which are spaced apart circumferentially about the axis (23). The orifices (110) are variable in size such that an orifice (110a) enlarges when a pair of adjacent orifices (110b and 110c) constrict upon relative rotation of the valve members from neutral positions. The pair of constricting orifices (110b, 110c) initially constrict at unequal rates, and subsequently constrict at equal rates until reaching fully constricted conditions.
