Abstract
A mixer valve has a valve cartridge arranged in interchangeable manner in a valve casing. A fixed control disk and a movable control disk can be moved counter to one another by an operating element in said valve cartridge. The latter has a roughly tubular casing, which is closed on the outside by a cup-shaped sleeve and on the inside by a cartridge bottom. As a result of this construction, the cartridge can be replaced particularly easily.
Claims22
A mixer valve comprising a valve casing having bores, a valve cartridge interchangeably mounted in said valve casing, a fixed control disk and a movable control disk for mixing fluids, mounted on said valve cartridge in operative association with an operating element having stop faces and a bearing ball and a transmitting element for converting the movement of said operating element into a movement of the movable control disk, said operating element projecting out of the cartridge and having its mobility limited by said stop faces for limiting the maximum possible temperature, said cartridge having a substantially tubular casing which is closed on the outside by a cup-shaped sleeve and on the inside by a removably mounted cartridge base, a cap nut radially fixing said sleeve in the valve casing and a partition fixed in said cartridge in which is shaped a lower part of a bearing for said bearing ball.
In a mixer valve wherein an operating element sets a flow rate of outflowing water and sets a mixing ratio between hot and cold water, and wherein a mixer casing has a stop for limiting the movement of the valve into a maximum temperature position so as to prevent unintentional scalding, the improvement which comprises stop faces limiting the movement of the valve into the maximum temperature position only when the valve is placed in a fully opened position, said stop faces allowing movement into the maximum temperature position so long as the valve is out of the fully opened position.
A mixer valve comprising
- a valve casing having a plurality of bores,
- an integral and partitioned valve cartridge interchangeably mounted in said valve casing, said valve cartridge having a substantially tubular casing which is closed on the outside by a cup-shaped sleeve and on the inside by a removably mounted cartridge base, said cartridge base having a plurality of bores which are adapted for connection with bores of said valve casing,
- a fixed control disk and a movable control disk mounted in said valve cartridge in operative association with an operating element having stop faces for limiting the movement of said mixer valve in the maximum temperature position when said mixer valve is completely open,
- a transmitting element for converting the movement of said operating element into movement of said movable control disk, and
- a cap nut radially fixing said sleeve in said valve casing.
