Abstract
A solenoid operated pinch valve including a housing and a hollow molded body coupled to said housing by a snap-on connection, a solenoid coil assembly seated within the housing, a plunger accommodated within said solenoid coil assembly for axial movement relative thereto controlled by energization of said solenoid coil assembly and between a pair of positions, said plunger having an end portion extending from the housing into said body and an opposite end portion received within said solenoid coil assembly, the body having a circumferential flange capable of being seated on one end of the housing and a pair of inflexible arms extending from the body in a coaxial direction relative thereto, said arms defining a passage for receiving a conduit across the path of movement of said plunger, a first orthogonal slot and a pair of resilient arms extending to the opposite end of the housing and engagable therewith in a snap-on coupling. One end of the plunger carries a second orthogonal slot. A flexible conduit having longitudinal ears unitary therewith is threadable thorugh the passage with the ears engaged within said orthogonal slots. A spring is provided for biasing the plunger against the flexible conduit to compress same closed, the solenoid coil assembly being energizable to move the plunger linearly against said bias by causing the plunger to pull the conduit open.
