Abstract
A three-way two-position poppet valve () comprising a housing () with a generally cylindrical valve chamber (), a first () and a second () port with coaxialvalve seats () at the ends of the chamber, and a third lateral working port (). A poppet body () is disposed reciprocably in the valve chamber so that in a first position of the poppet body the first valve seat () is sealed and the second port communicates with the working port, and in a second position the second valve seat () is sealed and the first port communicates with the working port. The valve is characterized in that the housing has two coaxial cylindrical passages () adjacent the respective valve seats, while the poppet body has two coaxial cylinder parts () slidingly and sealingly fitting the cylindrical passages, so that the poppet body is always supported in at least one of the cylindrical passages and fluid communication between the first and the second port is always prevented.
