Valve construction
First Claim
1. A combination of a source of fluid under pressure, a plurality of independent fluid distribution passageways and a valve intermediate said source and passageways for controlling fluid flows from said source to predetermined numbers of said passageways;
- said valve including a housing having a fluid inlet connected to said source and fluid outlets spaced from said inlet and being connected to corresponding fluid distribution passageways, and a valve piece mounted within said housing for movement between selected positions of adjustment, said valve piece being disposed intermediate said housing inlet and outlets and provided with first and second fluid passages communicating with said housing inlet and a first predetermined number of said housing outlets, when said valve piece is in a first selected position of adjustment, and a third fluid passage having one end thereof communicating with said second passage and the opposite end thereof terminating at the exterior of said valve piece and being spaced from said first and second passages;
the said opposite end of said third passage being in communication with said housing fluid inlet and said first passage being out of communication with said housing fluid inlet only when said valve piece is in a second selected position of adjustment, said second passage being in communication with said housing inlet and at least one housing outlet, when said valve piece is in either said first or second selected position of adjustment.

Abstract
A valve construction is provided for use in controlling fluid flow to a plurality of intake passageways. The valve construction is particularly suitable for use in an internal combustion engine to control the flow of exhaust gases to a turbocharger, the latter having a plurality of intake passageways communicating with the turbine section thereof. The valve construction includes a housing having an inlet for the engine exhaust gases and an outlet communicating with the intake passageways. Disposed within the housing and intermediate the inlet and outlet thereof is an adjustable valve piece which is adapted to be moved to selected positions of adjustment relative to said housing. When the valve piece is in a first selected position, exhaust gases flow through the housing to a first predetermined number of intake passageways. When the valve piece is adjusted to a second selected position, exhaust gases flow through the housing to a second predetermined number of intake passageways. The first predetermined number is of greater magnitude than the second predetermined number.
