Abstract:
1. An electromagnetic valve comprising: a housing having an inflow hole conduit through which a fluid flows in, an inner flow path communicating with the inflow hole conduit, and a discharge hole through which the fluid is discharged to an exterior; a valve seat secured in position inside the housing; a first valve adapted to abut one surface of the valve seat to shut off the fluid flowing into the inner flow path through the inflow hole conduit, the first valve having an internal passage to permit the fluid to flow therethrough; and a second valve provided coaxially with the first valve and adapted to control through adjustment of a dimension of a gap between the second valve and another surface of the valve seat, an amount of fluid flowing to the exterior of the housing through the discharge hole, wherein the housing is equipped with a whirling means for causing the fluid having flowed into the inner flow path through the inflow hole conduit to whirl in one direction; and, wherein said whirling means is comprised of said inflow hole conduit uniformly extending from the exterior of the housing a distance to and tangentially penetrating into said inner flow path, said inflow hole conduit terminating completely within said inner flow path, whereby said fluid circulates peripherally and adjacent to an outer wall surface of said inner flow path.
