摘要:
A pressure-sensor device (1) has: - a component sensitive to pressure, comprising a sensor body (5), with an elastically deformable membrane part (5a), and at least one detection element (6) for detecting a deformation of the membrane (5a); - a structure (2, 3) for housing or supporting the pressure-sensitive component, having at least one passageway (15) for a fluid the pressure of which is to be detected, the housing or supporting structure (2, 3) comprising a supporting body (2) with respect to which the sensor body (5) is positioned in such a way that its membrane part (5a) is exposed to the fluid coming out of the passageway (15), the supporting body (2) having a hydraulic-connection portion (2a) and a duct (14) that extends from the hydraulic-connection portion (2a); - at least one elastically deformable body (16), formed with one or more elastically deformable or compressible materials, comprising at least one from among: - a compressible compensation element (20, 21), configured for compensating any possible variations in volume of the fluid; - a sealing element (13, 17); configured for providing a seal with respect to at least one of the housing or supporting structure (2, 3), and the sensor body (5); and - a supporting element (23), configured for supporting or positioning the sensor body (5) with respect to the housing or supporting structure (2, 3).
At least one from among the compressible compensation element (16), the sealing element (13, 17) and the supporting element (23) is overmoulded on at least one of the housing or supporting structure (2, 3) and the sensor body (5).
摘要:
A hydraulic control and/or safety device, particularly for utility apparatuses or systems or appliances, which is preferably able to carry out a flow shut-off and/or limitation, particularly in the event of fault of the utility apparatus or system or appliance, and/or one or more features that improve the device and/or the apparatus performance. In particular, the device can carry out the function of the fluid treatment, so as to be particularly reliable, as it prevents at least the formation of deposits on its mechanical components designed to limit the water flow.

A washing agent dispenser for machines for washing includes a dispenser body with a receptacle for containing a washing agent, a lid having a lid body mounted in a guided way with respect to the dispenser body for being movable between a position of closing and a position of opening of the receptacle, and sliding guides between the dispenser body and the lid body. The sliding guides include: a first guiding element and a first guided element; and a second guiding element and a second guided element. At least one of the dispenser body and the lid body includes at least one constraint element, which is additional to the first walls and second walls and is pre-arranged for limiting displacements of the guided elements with respect to the guiding elements in a direction generally transverse to a direction of sliding of the lid determined by the sliding guides.

The present invention relates to a switch (1, 1A, 1B) for vehicles, in particular of the type adapted to be actuated by a linkage or kinematic system of the vehicle, used for signalling an operating condition, comprising: a body (2), electric terminals (3,4) housed within said body, an actuation element (10,10A,10B) at least partly movable within said body (2) when subjected to a control action, so as to put at least two of said electric terminals (3, 4) in electric contact with each other, wherein the actuation element (10,10A,10B) is at least partly deformable when a higher stress is applied thereto than necessary for closing the contact between the electric terminals.
摘要:
A washing-agent dispenser (1) for a household washing machine comprises a main casing (2), defining at least a container (3) for a washing agent, and a member (4') for closing said container (3). The closing member (4') comprises a substantially rigid body (4a') made of a first material, associated to which there are sealing means (16'), made at least in part with a second substantially elastic or soft material. Associated to the rigid body (4a') of the closing member (4') there are at least partially elastic or compliant complements (17', 18', 400), which are functionally distinct from the sealing means (16') and are able to undergo deformation in the course of the use of the closing member (4'). The additional complements (17', 18', 400) are made at least in part of an elastic, or soft, or compliant material, in particular of a synthetic type, which can be overmoulded directly on the rigid body (4a') of the closing member (4'). Preferably, a plurality of additional complements (17', 18', 400) is formed in a single component, which can include also said sealing means (16').
摘要:
A door-lock device for a household appliance comprises a body (2) to which there is hinged, via a pin (8), a catch (7) that is capable of angular movement, as well as an actuating system (3-5) having actuator means (3) that can be controlled to determine passage of the locking member (7) between a first inoperative condition, in which opening of the door (9) of the household appliance is enabled, and an operative condition, in which opening of the door (9) is prevented. Switching means (14) are provided for enabling translation of the pin (8), and hence of the catch (7), between a position of normal operation and a position of special operation, both of which stable. In the position of normal operation, the movement of the catch (7) is obtained via the actuating system (3-5), whilst in the position of special operation the catch (7) can assume a second inoperative condition. The switching means (14) can be actuated by applying on the door (9) a force that is considerably greater than the minimum force necessary for opening the door itself when the catch (7) is located in its first inoperative condition.
摘要:
Household apparatus, in particular a washing machine, comprising an electrochemical treatment device (20), in particular a water softener, in which two electrodes (20B,20C) are provided, with ion exchange membranes (C,A) arranged between them for delimiting a plurality of channels (CE,CC,CP). According to the invention, means ( + ,- ) are provided for periodic filling of some channels (CE,CC,CP) of the electrochemical device (20) with a cleaning substance or solution, the latter being apt to dissolve and/or remove saline precipitates eventually formed inside the device .
