Abstract
A governor valve for an automatic transmission comprising a valve body and a body support secured together and for rotation with an output shaft of the transmission. A line pressure passage connected to pressured fluid in the transmission and a governor pressure passage for operating the governor are formed in the body support, and passage means in the governor body connects the line pressure passage to the governor pressure passage. A normally closed valve is disposed in the passage means and normally blocks communication between the line pressure passage and the governor pressure passage, and the valve is operable to open in response to centrifugal force imparted thereto during rotation of the shaft to communicate the line pressure passage with the governor pressure passage and to actuate the governor. The passage means includes a bore in the governor valve body which is inclined relative to the axis of rotation of the shaft, and a strainer is disposed in the bore to prevent foreign matter from entering the valve.
