The valve of a liquid fuel pressure regulator comprises a two-part construction consisting of a spherically contoured element and a stem. The spherically contoured element serves to swivelly mount the valve on the movable wall which carries the valve. The spherically contoured element comprises a hole which is on a radial to the center of the element. The shank of the stem is press-fitted to this hole to dispose the stem's flat circular head toward a seat with which the valve coacts as the pressure regulator operates. The swivel mounting compensates for misalignment and out-of-squareness of the valve travel relative to the seat and enables the head to close flat against the seat. Two embodiments are disclosed. In one, the spherically contoured element is a sphere and the hole is a blind hole drilled into the sphere. In the other, the spherically contoured element is a truncated sphere and the hole is a through-hole.

An electro-magnetically actuated pawl clutch is adapted to establish a fixed overdrive ratio in a powersplit type hybrid gearing arrangement. The electro-magnetically actuated clutch includes a first race splined to the transmission input shaft and a second race integrally formed into a first gear that is supported for rotation about the input shaft. Electrical current in a non-rotating coil establishes a magnetic field in the first race. The magnetic field causes a set of pawls to pivot with respect to the first race and to engage a cam surface in the second race. The pawls and cams are designed such that, when engaged, the second race can rotate faster than the inner race but cannot rotate slower. The first gear meshes with a second gear fixed to the transmission output shaft.
