Pressure regulator valve

A pressure regulator valve assembly, for a land motor vehicle transmission, which limits excessively high line pressure and is designed to fit into an existing valve body casing bore comprising:

• a. a valve body;
• b. a valve snout, attached to said valve body, further comprising an inner end and outer end;
• c. a ball, placed inside said valve body and seated to said inner end of said valve snout, which prevents pressure to leak into the valve body unless a certain maximum pressure is achieved;
• d. a spring, placed inside said valve body and attached to said valve body contacting said ball, which holds said ball in place unless pressure greater than that of its force on said ball is achieved;
• e. lubricating means for lubricating inner portions of said valve body between said ball and inner walls of said valve snout that prevents excessive wear;
• and,
• f. plugging means for sealing the end opening of the valve body casing bore in which the pressure regulator valve assembly resides, said plugging means utilize an o-ring for a more positive seal and prevent pressure from escaping through the valve body casing bore.
