Abstract
The invention pertains to a valve particularly suitable for sampling internal combustion engine lubricating oil while under pressure being used within the engine and consists of a valve body placed within a pressurized oil conduit. The body includes an orifice having a valve movable between open and closed positions by a sample collecting receptacle wherein one hand operation is readily achieved. The valve includes a proboscis suitable for piercing the sample receptacle diaphragm, and a spring produces a positive biasing force on the valve toward the closed position. A pressure balancing piston connected to the valve balances the force necessary for valve operation due to internal pressure. A removable cover protects the valve and proboscis when not in use.
Claims11
A fluid sampling valve for internal combustion engines and the like, comprising, in combination, a body, a passage defined in said body having an inlet and an outlet, a valve element receiving orifice defined in said body intersecting said passage, a valve element within said orifice movable between open and closed positions wherein fluid within said passage flows through said orifice when said valve element is in said open position, pressure balancing means defined on said valve element in communication with said passage and sample collecting container engaging means defined upon said valve element for actuation of said valve element between said open and closed positions by a sample collecting container.
