Description

DESCRIPTION

Solenoid valve for fluid supply and regulation

OBJECT OF THE INVENTION

The purpose of this application is to register a solenoid valve for the supply and regulation of fluids.

More specifically, the invention proposes the development of a solenoid valve for the supply and regulation of fluids that has a solenoid with a non-circular plant and outdated moving core with respect to a central position.

BACKGROUND OF THE INVENTION

Electric actuating valves intended to be mounted on a variable displacement oil pump, which is part of an internal combustion engine of a vehicle, are well known in the state of the art.

This type of solenoid valve essentially comprises a primary body with a substantially cap-shaped shape that houses inside a solenoid to act electromagnetically on a mobile core and a secondary body attached to the primary body, provided with at least one input socket and at least one outlet through which a fluid circulates, and where sealing means connected to the mobile core are housed and internally displaced. The solenoid has a general cylindrical shape, thus being its circular plan.

Although the cylindrical shape with solenoid circular plan is suitable for this type of solenoid valve, due to the configuration and dimensions that various components that are arranged around the solenoid valve in a vehicle engine may have, this cylindrical shape can make assembly difficult of the solenoid valve, which may involve the dimensional change of other components to be installed around the solenoid valve, which would imply an increase in manufacturing costs or having to reduce the solenoid dimensions, which could affect the performance of solenoid valve operation due to not having the same performance due to the reduction of solenoid size.

In addition, the applicant is not currently aware of an invention that has all the features described herein.

DESCRIPTION OF THE INVENTION

The present invention has been developed in order to provide a solenoid valve that is configured as a novelty within the field of application and resolves the aforementioned drawbacks, also providing other additional advantages that will be apparent from the accompanying description. continuation.

It is therefore an object of the present invention to provide a solenoid valve for the supply and regulation of fluids, comprising an internally hollow primary body in which a solenoid intended to act electromagnetically on a mobile core and a secondary body is housed inside. internally hollow attached to the primary body, said secondary body being provided with at least one inlet and at least one outlet through which a fluid circulates, in which sealing means connected to the core are housed and internally displaced mobile, the mobile core comprising an axially movable axis, and is essentially characterized by the fact that the solenoid has a polygonal plan contour, the axis being offset with respect to the center of one of the coordinate axes (X, Y).

Thanks to these characteristics, a valve is obtained with a solenoid with a non-circular plant that can be mounted in locations in which a valve of this type with a circular plant solenoid and the same magnetic field force could not be installed for reasons lack of space and without the need to substantially modify the rest of the valve body or other components present around the valve when mounted in a mechanical environment.

Preferably, the polygonal plant is rectangular, although there is also the possibility that the polygonal plant is quadrangular.

According to another aspect of the invention, the primary body and the secondary body are connected to each other through a threaded portion present in the primary body that is complementary to a threaded portion present in the secondary body.

The solenoid valve described thus represents an innovative structure with structural and constitutive characteristics unknown until now for the purpose to which it is intended, reasons that, together with its practical utility, provide it with sufficient grounds to obtain the privilege of exclusivity that is requested.

Other features and advantages of the solenoid valve object of the present invention will be apparent from the description of a preferred but not exclusive embodiment, which is illustrated by way of non-limiting example in the accompanying drawings, in which:

DESCRIPTION OF A PREFERRED EMBODIMENT

In view of the aforementioned figures and, according to the numbering adopted, an example of a preferred embodiment of the invention can be observed therein, which comprises the parts and elements indicated and described in detail below.

Thus, an exemplary embodiment of a proportional valve for the supply and regulation of oil, indicated in general with reference (1), is provided for the supply of oil from a cooling system for a combustion engine, comprising a body primary (2) which has a substantially internally hollow cap shape in which is housed inside a coil holder (3) (rectangular) that supports a solenoid (4) intended to act electromagnetically during operation on a mobile core (5) and a secondary body (6) with a shape elongated cylindrical overall which is also internally hollow attached to the primary body (2). Sealing means are part of the mobile core, so depending on the travel of the mobile core by the magnetic field generated, the shutter means will act on the input and / or output sockets defined by through holes made at secondary body length (6).

A coil core (10) is provided to close the magnetic circuit generated by the solenoid (4), which has a substantially C-shaped cross section (see Figure 4), such that laterally it is only overlapped on one of the side walls defined by the solenoid (4).

The solenoid (4) is electrically connected to an external source by connectors connectable in an extension (20) that protrudes from the primary body (2).

As can be seen more clearly in Figure 2, the solenoid (4) has a polygonal plan contour, the axis that is part of the moving core displaced by an offset (d) with respect to the center of one of the coordinate axes (X, Y). Similarly, the fixed core is also offset with respect to the center of one of the coordinate axes. This design facilitates the assembly of the solenoid valve (1) as it allows the provision of a screw (not shown) in the hole (11) without the solenoid itself hindering its placement unlike what would happen in case of using a solenoid of circular plan

Mention that between the mobile core (5) and the fixed core (7) a first longitudinally arranged return spring (8) is provided and is housed in housings present in the mobile core (5) and the fixed core (7).

Additionally, a second spring (9) located at the bottom of the solenoid valve (in accordance with the orientation shown in the figures) is provided, which stops and is mounted on an inner shoulder (120) that is part of an element (12 ) threadedly coupled to the secondary body (6).

As can be seen in detail in Figure 3, the connection between the primary body (2) and the secondary body (6) is carried out during the assembly process through a threaded portion (21) present in the primary body ( 2) which is complementary to a threaded portion (61) present in the secondary body (6).

The details, shapes, dimensions and other accessory elements used in the manufacture of the solenoid valve of the invention may be conveniently replaced by others that do not depart from the scope defined by the claims included below.
