A washing agent dispenser for washing machines comprises a fixed dispenser part () and a removable dispenser part (). The removable dispenser part () comprises a hollow body () defining a tank for a washing agent. The tank has, in a lower part thereof, an outlet (), in a back wall of the hollow body (), which is couplable in a separable way to an inlet () at the front of the fixed dispenser part (). A retention valve () is mounted on the hollow body (), in a position corresponding to the outlet () of at the tank. The retention valve () is configured to assume a respective open position following upon coupling between the outlet () and the inlet (), and to assume a respective closed position following upon uncoupling between the outlet () and the inlet ().

Washing agent dispenser for dishwashing machines

A dispenser of washing agents for washing machines has a first tank, to contain a first washing agent, and a first dispensing arrangement, to dispense first dosed amounts of the first washing agent. The first dispensing arrangement has a peristaltic pump, which is configured to be driven in a first direction of rotation to cause delivery of the first dosed amounts of the first washing agent. The dispenser has a second tank, to contain a second washing agent, and a second dispensing arrangement, to dispense second dosed amounts of the second washing agent. The peristaltic pump has a command arrangement of the second dispensing arrangement, and is configured to be driven in a second direction of rotation, to drive the command arrangement so as to cause dispensing of the second dosed amounts of the second washing agent.

A bearing detection device comprises a housing body, to be fixed to a stationary ring of a bearing, and a detection arrangement on the housing body, comprising a piezoelectric transducer. The detection arrangement also comprises: a floating body, mounted on the housing body and suitable for mechanically transmitting vibrations of the bearing, and a sensor unit, which is mounted in a stationary position on the housing body and has a detection surface configured for receiving thereon a corresponding surface of the floating body. The piezoelectric transducer defines at least part of the detection surface and is configured for generating an electrical potential difference that is substantially proportional to the magnitude of a stress exerted by the floating body on the piezoelectric transducer.

Detection device for bearings

A level sensor comprises an electrical-connection structure and a level-detection structure. The level-detection structure comprises a plurality of elongated electrodes, which include at least three measuring electrodes. The elongated electrodes extend at least partially in side-by-sidey positions in a length direction of the level-detection structure and each have a proximal end and a distal end relative to the electrical-connection structure. The level-detection structure is divided, in the length direction, into a succession of detection sections, each of which includes two effective portions of two respective measuring electrodes, the two effective portions extending to a prevalent extent substantially parallel and equidistant, at a first predetermined distance from each other, in the length direction. In the detection sections there also extends, in the length direction, a non-effective portion of one further elongated electrode other than the two measuring electrodes that define the two effective portions of the corresponding detection section, the at least one further elongated electrode being one measuring electrode or else a reference electrode. The elongated electrodes are shaped in such a way that, at one or more of the detection sections, the non-effective portion of the at least one further elongated electrode extends to a prevalent extent at respective second predetermined distances from the corresponding two effective portions, the second predetermined distances being greater than the first predetermined distance.

Level sensor for detecting the level of a medium

A sensorized supporting device for bearings () comprises: &#x2022; a bearing housing (), configured for being secured to a mounting structure and defining at least one seat () for a bearing (); and &#x2022; a sensorized supporting base (), having a supporting body (') prearranged for being at least partially positioned between the mounting structure (S) and the bearing housing (). The supporting body (&#x2032;) has a detection surface () which extends in a longitudinal direction (L) and a transverse direction (W) and is configured for resting, directly or via interposition of at least one further element, on a corresponding surface of one of the bearing housing () and the mounting structure, the supporting base () being provided with a mechanical-stress sensor. The mechanical-stress sensor comprises at least one piezoelectric transducer () defining at least part of the detection surface (), the at least one piezoelectric transducer () being configured for generating an electrical potential difference that is substantially proportional to the magnitude of a mechanical stress (SS) applied to the bearing housing ().
