Abstract
A pressure reducing solenoid valve according to an exemplary embodiment of the present invention includes: a pump housing which has an inflow path and an outflow path; a coil which is provided at an upper side of the pump housing; and a pressure reducing operating unit which has an upper portion positioned in the coil, and a lower portion positioned in the pump housing, and allows a fluid to be discharged from the inflow path to the outflow path so as to reduce pressure.
Claims13
A pressure reducing solenoid valve comprising:
- a pump housing which has an inflow path and an outflow path;
- a coil which is provided at an upper side of the pump housing;
- and
- a pressure reducing operating unit which has an upper portion positioned in the coil, and a lower portion positioned in the pump housing, and allows a fluid to be discharged from the inflow path to the outflow path so as to reduce pressure,
- wherein the pressure reducing operating unit includes:
- an outer sleeve which surrounds an inner sleeve, and is provided in the coil;
- the inner sleeve which is provided in the outer sleeve;
- a plunger which is provided in the inner sleeve, and moved downward by electromagnetic force that is generated when an electric current is applied to the coil;
- and
- a stator which is positioned below the plunger, has an upper portion disposed in the inner sleeve, and a lower portion disposed in the pump housing, and provides a flow path through which the fluid flows from the inflow path to the outflow path, and
- wherein an opening and closing member, which opens and closes a through hole provided in an upper portion of the inner sleeve, is provided on an upper portion of the plunger.

A pressure reducing solenoid valve comprising:
- a pump housing including an inflow path and an outflow path;
- a coil disposed over the pump housing;
- and
- a pressure reducing operating unit including an upper portion and a lower portion, the upper portion being disposed in the coil, the lower portion being disposed in the pump housing, the pressure reducing operating unit allowing a fluid to flow from the inflow path to the outflow path when a current is applied to the coil,
- wherein the pressure reducing operating unit includes:
- an inner sleeve disposed in the coil and including a through hole, the through hole being disposed in an upper portion of the inner sleeve;
- a plunger disposed in the inner sleeve and moving away from the through hole of the inner sleeve when the current is applied to the coil;
- and
- an opening and closing member disposed on an upper portion of the plunger, the opening and closing member opening the through hole of the inner sleeve when the current is applied to the coil and closing the through hole of the inner sleeve when the current is not applied to the coil.
