Abstract
A chained multiple connection change-over valve assembly of an extremely compact form in thickness, formed by connecting a plural number of multiplex change-over valve units of a flatly thin shape successively in a lateral direction, each change-over valve unit containing a plural number of fluid switching mechanisms within a valve casing side by side in a transverse direction and having a plural number of output ports on a front face of the valve casing in a row in the transverse direction.
Claims6
A multiple connection change-over valve assembly, comprising:
- a plural number of laterally connected multiplex change-over valve units each of a flatly thin shape;
- said multiplex change-over valve units each constituted by:
- a valve casing of a flat shape measuring smaller in height than in width, the height of said valve unit being of a minimum necessary dimension for accommodation of one fluid switching mechanism or one output port whichever has a larger dimension in the vertical direction of said valve casing;
- a plural number of fluid switching mechanisms built into said valve casing side by side in the transverse direction thereof for switching flow directions of a pressurized fluid;
- joint faces provided on the opposite lateral sides of said valve casing for directly connecting said change-over valve unit to adjacent valve units;
- pressurized fluid supply and discharge passages opened in the joint faces in communication with the respective fluid switching mechanisms for supplying and discharging said pressurized fluid;
- and
- a plural number of output ports provided on a front face of said valve casing in a row in the transverse direction and in communication with the respective switching fluid mechanisms.
