<p>A valve for mixing two fluids of different viscosity, is integral with a pump, and has a sliding control element (50). The first inlet channel (36) passes through a guide channel (52) on the slider. One end of the pump chamber is connected to the outlet channel (40), and the other end connected to a second inlet channel (34). The slider is subjected to pressure on one side by a valve spring (60) and the low pressure fluid in the second inlet channel (24). On the other side it is subjected to the higher pressure of the fluid in the outlet channel in front of a throttle (42). The slider has a sloping edge (58) controlling flow through the first inlet channel.</p> |
