Abstract
A solenoid valve has a valve body with an inlet and an outlet and a valve seat therebetween. A valve member is selectively engageable with the valve seat for controlling the flow of fluid from the inlet to the outlet. A biasing device is engageable with the valve member for holding the valve member against the valve seat. A solenoid assembly is mounted upon the valve member for moving the valve member away from the valve seat. A mounting arrangement is interposed between and connects the valve body and the solenoid assembly in a rotary, frictional engagement.

In a solenoid valve having a valve body with an inlet and an outlet and a valve seat therebetween, a valve member selectively engageable with the valve seat for controlling the flow of fluid from the inlet to the outlet, a biasing device engageable with the valve member for holding the valve member against the valve seat, and a solenoid assembly mounted upon the valve member for moving the valve member away from the valve seat, the improvement comprising:
- a mounting arrangement interposed between and connecting the valve body and the solenoid assembly in a rotary, frictional engagement,
- wherein the mounting arrangement includes a mounting bracket positioned upon the valve body, and a snap plate located between the solenoid assembly and the mounting bracket.
A modular, solenoid operated, liquid dispensing valve comprising:
- a valve body having an inlet and an outlet for respectively introducing liquid into and delivering liquid out of the valve body, and a valve seat between the inlet and the outlet;
- a valve member selectively engageable with the valve seat for controlling the flow of liquid from the inlet to the outlet;
- a biasing device engageable with the valve member for holding the valve member against the valve seat;
- a solenoid assembly mounted upon the valve body for selectively moving the valve member in a direction away from the valve seat;
- and
- a mounting bracket positioned between the valve body and the solenoid assembly for supporting the solenoid thereon,
- wherein at least the mounting bracket is removably connected to the valve body by a twist, snap fit.
A method of assembling a solenoid valve comprising the steps of:
- a) providing a valve body having an inlet and an outlet for controlling fluid through the valve body, and a valve seat between the inlet and the outlet;
- b) providing a valve member selectively engageable with the valve seat for controlling flow of fluid from the inlet to the outlet;
- c) providing a biasing device engageable with the valve member for holding the valve member against the valve seat;
- d) providing a solenoid assembly mounted upon the valve body for selectively moving the valve member in a direction away from the valve seat, the solenoid assembly including a solenoid in a frame for holding the solenoid therein;
- e) providing a mounting bracket to be positioned between the valve body and the solenoid assembly;
- f) connecting the mounting bracket to the valve body by means of a first twisting, snap fit;
- and
- g) connecting the solenoid assembly to the mounting bracket and the valve body by means of a second twisting snap fit, whereby rotational position of the mounting bracket relative to the valve body and rotational position of the solenoid assembly relative to the valve body and the mounting bracket are variably adjustable.
