Appl. No.:

10/302195

Inventors:

Louis A. Pacinelli - Wyncote PA 19095

International Classification:

F01L 320

US Classification:

1231883, 1231888, 1231889, 123 905

Abstract:

An intake and exhaust valve for an internal combustion engine is provided wherein the stem longitudinal axis is offset from the valve head center. Alternatively, the valve head may have an end having a planar surface wherein the axis and the surface are not perpendicular. Alternatively, the valve head may have an irregular perimeter having a straight edge, and another edge being rounded and generally radiused to the straight edge. Alternatively, the valve head may have a stepped, non-planar shape with respect to the plane of the face of the head. Alternatively, the valve head may have a shape that is pie-shaped. Alternatively, the stem longitudinal axis may be offset from the center point of the valve head, and the valve head may have an end having a planar surface, wherein the longitudinal axis and the planar surface are not perpendicular to one another.

Abstract:

A compensating torque wrench device used for tightening an internally threaded member (e. g. , a nut) to an externally threaded member (e. g. , a bolt). The internally threaded member is of conventional construction while the externally threaded member includes a free end having a recess. The device includes a working end having first engagement means which engages the internally threaded member and second engagement means comprising a rotatable projection for engaging the recess of the externally threaded member. The device also includes first and second rotational means and a driven end (e. g. , a handle), such that the driven end is connected to the first engagement means by the first rotational means and to the second engagement means by the second rotational means. When force is applied to the handle, the first rotational means exerts a first torque on the first engagement means causing it to rotate in the first rotational direction and causes the second rotational means to exert a second torque on the second engagement means, causing it to rotate in the opposite rotational direction. The device also includes torque measuring means which indicates the amount of torque being applied to the nut and bolt, respectively.
