HOUSEHOLD APPLIANCE HAVING SOLENOID VALVE Russian patent published in 2018 - IPC F16K31/40 

FIELD: machine building.

SUBSTANCE: household appliance (100) with solenoid valve (101) for controlling the flow rate or pressure in a discharge conduit includes membrane (103) having pilot port (105), control pin (107) having sealing head (115) for closing pilot port (105) and spring means (109) for urging control pin (107) with a force. When opening pilot port (105), hydraulic resistance at pilot port (105) varies depending on the distance between sealing head (115) and pilot port (105). Control pin (107) includes rod (113) extending inside the pilot port (105). Rod (113) protrudes from sealing head (115) and has a diameter smaller than the diameter of pilot port (105), so that when pilot port (105) is open, the hydraulic resistance sensitivity of pilot port (105) with respect to the position of control pin (107) is reduced. Rod (113) is formed on sealing head (115) for sealing pilot port (105), rod (113) being integral with sealing head (115).

EFFECT: present invention relates to a household appliance with a solenoid valve having a membrane.
