Electromagnetic Valve Fluid Connection Arrangement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional electromagnetic valve devices face challenges in optimizing the axial extent of the valve housing while maintaining a maximum usable plunger width, due to restricted installation space and the geometry of fastening means, which limits the force application area for the booster effect and necessitates arranging fluid connections on opposite sides of the fastening bores.
Innovation Solution
The design allows the fluid inlet and working connections to be positioned on a common axial side relative to the fastening means, enabling them to be arranged adjacently or offset radially/axially, maximizing plunger width and optimizing the axial extent of the valve housing, while the plunger can move within the fluid connections, and additional fluid connections can be integrated for continuous mechanical coupling and improved sealing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Force
If the plunger means are positioned axially to continue the armature means in the valve housing, then the mechanical assistance effect of the booster technology is achieved, but the axial installation space of the valve housing increases
Solution Approach 1:
The invention repositions the fluid inlet connection and fluid working connection from opposite sides of the fastening means to a common axial side, and offsets them radially instead of axially. This dimensional change in connection arrangement allows the plunger means to be positioned radially between the fastening bores rather than axially continuing the armature, thereby achieving the booster effect while reducing axial extent.
2Ease of manufacture
If the fastening means geometry is based on standardized holes or bores, then ease of manufacture is improved, but the transverse extent of the plunger means and force application area are limited
Solution Approach 1:
The invention maintains standardized fastening bores for ease of manufacture but creates a locally optimized force application area by positioning the plunger means radially between the bores. The fluid inlet connection and fluid working connection are offset radially to provide adequate radial space for the plunger while keeping the fastening geometry standardized.
3Volume of moving object
If the fluid inlet connection and fluid working connection are arranged on opposite sides of the fastening means, then the plunger means can be accommodated between the bores, but the total axial extent of the device increases
Solution Approach 1:
The invention changes the arrangement from axial separation of fluid connections to radial offset. Both the fluid inlet connection and fluid working connection are positioned on the same axial side of the fastening means but offset radially, allowing the plunger means to be accommodated radially between the bores rather than axially, thereby reducing total axial extent.

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This configuration enhances the mechanical assistance effect of the booster technology, reduces the overall axial extent of the valve housing, and allows for a more compact, flexible, and reliable valve system suitable for various applications, including motor vehicles, by optimizing the geometric arrangement of fluid connections and fastening geometry.
Implementation Method 1
the armature means effect the switching movably in response to the energizing of stationary coil means in the valve housing
Implementation Method 2
the fluid pressure of the fluid flowing into the inlet connection overcomes a counter force (generated by a preloading spring or similar energy storage means, for instance) of the plunger means and moves them

AI summary
The invention relates to an electromagnetic valve device having an armature (18) which is moveable in an axial direction in a valve housing (10) in response to energizing of a stationary coil (12), and which is designed to interact with a first valve seat (22) associated with a fluid inlet connection (26) of the valve housing, a first fluid flow path (36) being formed in the valve housing such that fluid flowing through the opened first valve seat can flow in order to actuate a plunger (32) moveable relative to the armature (18) and to which a preloading force is applied, the actuation causing a second valve seat (43) interacting with the plunger (32) to be opened to produce a fluid connection to a fluid working connection (42) of the valve housing, and the valve housing having a fastening structure (44, 46) in the form of at least one hole extending at an angle to the axial direction, the fluid inlet connection (26) and the working connection (42) being formed on the same axial side of the valve housing in relation to the structure means.
