Abstract
A coil assembly housing for housing the actuator of a stepper motor valve includes a snap feature for snap fitting the coil assembly housing to a valve house assembly, wherein the snap feature includes at least one protrusion pointing radially inward of the coil assembly housing, wherein the protrusion is provided for interacting with a recess of the valve house assembly, and wherein the protrusion is held inside the recess by a wall of a valve block, into which the valve house assembly and the snap feature are insertable. The disclosure also pertains to a valve house assembly, a valve block and a stepper motor valve having such components.
Claims2
A stepper motor valve, comprising:
- a coil assembly housing for housing an actuator of the stepper motor valve, the coil assembly housing comprising a snap feature for snap fitting the coil assembly housing to a valve house assembly, wherein the snap feature comprises at least one protrusion pointing radially inward of the coil assembly housing, wherein the protrusion is provided for interacting with a recess of the valve house assembly, and wherein the protrusion is held inside the recess by a wall of a valve block, into which the valve house assembly and the snap feature are insertable, and
- the valve house assembly comprising at least one valve house assembly recess for interacting with the protrusion of the coil assembly housing, and a valve block wherein an interior cylindrical wall is provided for interacting with the snap feature of the coil assembly housing, wherein the coil assembly housing is connected to the valve house assembly by means of the snap feature and the valve house assembly recess and wherein the snap feature is held in the valve house assembly recess by the valve block.
