Abstract
A cartridge type mixing valve is disclosed. A pin and groove arrangement is provided between an operating spindle and a plastic drive member to effect a linear movement of a valve disk. Wall members provide the groove arrangement, and additional interconnected wall members afford stability with a reduction of plastic material. Force load distribution on the drive member is effected by means of lateral extensions of the pin and groove. The pin is made integral so that a reduced size mixing valve can be achieved without loss of control over the drive member.
Claims6
A fluid valve, comprising:
- a valve body having an axial bore suitable for fluid communication with an inlet and outlet;
- a stationary valve element having at least first and second fluid inlet pathways, and a movable valve element, both elements being positioned in the axial bore for regulating fluid flow of first and second fluids in response to movement of the movable element over the stationary element;
- and
- a rotatable and pivotable spindle extending into an upper end of the axial bore of the valve body, the spindle having one end extending outside the valve body and the other end extending into a recess in a drive member that is separately formed from the movable valve element, the drive member operatively engaging the movable valve element;
- whereby connection of the spindle to the drive member comprises an essentially horizontally extending pin extending laterally outward from the spindle and, rotatable therewith, and an upwardly open transverse groove in the drive member for receiving the pin so that rotation of the spindle on its longitudinal axis can rotate the drive member and said pivoting of the spindle can laterally shift the drive member, said open transverse groove provided by two opposing wall portions which are interconnected by two additional wall portions;
- and
- wherein there is also an adapter connected to the spindle by a pivot member, the adapter and drive member sandwiching the pin with the pin being entirely housed within the drive member.
