Title:
FLOW REGULATING GROOVE COMPONENT
Document Type and Number:
WIPO Patent Application WO/2018/072658
Kind Code:
A1
Abstract:
A flow regulating groove (2) component comprising a body (1). The flow regulating groove (2) is provided on the body (1). The design in which the width (L1) of an opening of a groove body (20) is less than the maximum width (L) of the cross-section of the groove body (20) reduces the proportion of a sealing pad distending and protruding into the flow regulating groove (2) under pressure, thus mitigating the impact that the sealing pad distending and protruding into the flow regulating groove (2) has on the actual cross-sectional area of the flow regulating groove (2) for a liquid to flow through. A staggered segment (23) can form a support for the sealing pad, thus further reducing the proportion of the sealing pad distending and protruding into the flow regulating groove (2) under pressure, and further mitigating the impact that the sealing pad distending and protruding into the flow regulating groove (2) has on the actual cross-sectional area of the flow regulating groove (2) for the liquid to flow through.
