    摘要: Spherical ball drive mechanism for directly coupling a rotary force motor to a valve member, includes a spherical bearing assembly at one end of the valve member. The spherical bearing assembly consists of an outer race member having a concave spherical inner bearing surface and a spherical bearing member having a convex spherical outer bearing surface complementary to the concave spherical inner bearing surface of the outer race member and received therein. The outer race member has a longitudinal axis substantially perpendicular to the longitudinal axis of the valve member and a transverse center axis radially offset from the longitudinal axis of the valve member. An eccentric output shaft of the rotary force motor extends substantially perpendicular to the longitudinal axis of the valve member for receipt in a longitudinal bore in the spherical bearing member.

    摘要: An adaptive stepped compensator valve for controling hydromechanical control apparatus having high and low pressure control lines. The adaptive stepped compensator valve includes a housing having an elongated bore and a plurality of ports formed therein, a sleeve, disposed in sealed slidable engagement with the housing in the bore, and having an opening formed therein extending the length of the sleeve and direct acting main and balance spools disposed in the opening. High pressure fluid is inputed into a first chamber of the valve formed by the main spool and a second chamber formed by a balance spool. Low pressure fluid is inputted into a third chamber formed by an end of the main spool which abuts an end of the balance spool. The invention outputs a control signal based upon a detected difference in pressure between the high pressure fluid and the low pressure fluid. An adaptive operation of the valve is accomplished by axial movement of the sleeve which controls the amount of fluid outputted as a control signal by the valve. Stepped operation of the valve is accomplished by balancing the valve by inputting high pressure fluid in the first and second chambers of the valve.
