Valve Group Shutter Mechanism for High Viscosity Oil
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing valve groups in vehicle oil circuits fail to maintain stability and effectiveness when dealing with high viscosity oil, leading to breakage and malfunctions.
Innovation Solution
A valve group design featuring a shutter mechanism housed in a conduit, controlled by a control device that adjusts oil flow based on viscosity, ensuring high resistance and efficient management even with high viscosity oil, with a failsafe mechanism for actuator failures.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional valve groups are used in oil circuits, then normal oil flow management is achieved, but the valve groups fail and break when oil viscosity increases
Solution Approach 1:
The patent applies beforehand cushioning by providing a failsafe mechanism that automatically activates when the actuator fails. The spring member is pre-loaded to keep the shutter in the open position, cushioning against the harmful effect of actuator failure and high viscosity oil that would otherwise cause the valve to jam in the closed position and lead to breakage.
2Ease of operation
If the valve group is designed to manage oil flow, then oil temperature and flow control is achieved, but the control mechanism fails under high viscosity conditions
Solution Approach 1:
The patent applies self-service by designing a system where the spring member automatically compensates for actuator failure without requiring external intervention. The shutter is self-actuated through the spring force, which naturally pushes it to the open position when the actuator can no longer maintain control, allowing the valve group to continue managing oil flow even when the control mechanism fails.
3Volume of moving object
If the shutter is positioned radially between the valve body and conduit side walls, then compact design is achieved, but the shutter may jam under high viscosity oil pressure
Solution Approach 1:
The patent applies beforehand cushioning by pre-loading the spring member to exert a constant force on the shutter, keeping it biased toward the open position. This cushioning force counteracts the high viscosity oil pressure that would otherwise push the radially positioned shutter against the conduit side walls and cause jamming, maintaining the compact design while preventing failure.

AI summary
The invention is a valve group (1) housable in a conduit (8) extending along a conduit axis (C-C) comprising conduit side walls (80) and a first conduit opening (81) and a second conduit opening (82) positioned axially spaced apart, fluidically connected to an operating group and a heat exchanger group (920), respectively. The valve group (1) extends in length along an axis (X-X) coinciding, in a housed configuration, with the conduit axis (C-C), and comprises: i) a valve body (2), comprising a body cavity (200) and a first body opening (21) and a second body opening (22) positioned axially spaced apart, so as to face, in a configuration of the valve group (1) housed in the conduit (8), the first conduit opening (81) and the second conduit opening (82), respectively, wherein the valve body (2) further comprises at least one guide slot (26) extending axially with respect to the axis (X-X); ii) a shutter (3) comprising a shutter body (30) fitted, axially movable, onto the valve body (2), radially positioned between the valve body (2) and the conduit side walls (80), wherein the shutter (3) comprises a first shutter opening (31) and a second shutter opening (32) and a guide element (36) extending radially through the guide slot (26); iii) a control device (4) engaged with the valve body (2) and the shutter (3) to control the axis (X-X) between a base position in which the hydraulic passage section defined by the alignment of the first shutter opening (31) with the first body opening (21) is greater than or equal to the hydraulic passage section defined by the alignment of the second shutter opening (32) with the second body opening (22), and an adjustment position in which the hydraulic passage section defined by the alignment of the first shutter opening (31) with the first body opening (21) is smaller than the hydraulic passage section defined by the alignment of the second shutter opening (32) with the second body opening (22).
