Pressure equalizing insert
First Claim
1. A valve (10) for regulating a fluid stream in particular in an HVAC system, wherein the valve (10) has installed a valve element (12) for regulating the fluid stream, wherein the valve (10) has installed a pressure equalizing insert (1), wherein the pressure equalizing insert (1) is a preassembled module, wherein the pressure equalizing insert (1) comprises a housing (2) having an actuating member (3) displaceably mounted thereon and equipped to at least partially guide the fluid stream regulated by the valve (10), wherein the housing (2) has a first housing part (21) connected to a second housing part (22), wherein a membrane (6) is secured between the first housing part (21) and the second housing part (22), wherein the membrane (6) holds displaceably the actuating member (3), and wherein the actuating member (3) cooperates with a valve seat (15) to regulate the fluid stream as a function of a pressure difference prevailing in the fluid stream, wherein the pressure difference depends on a position of the valve element (12), wherein a first housing part (8) of the valve (10) comprises a first flange (8f) for connecting said valve to a first pipe, and a second housing part (9) of the valve (10) comprises a second flange (9f) for connecting said valve to a second pipe, and wherein said first flange (8f), said second flange (9f) and the pressure equalizing insert (1) are arranged in a coaxial configuration.

Abstract
The invention relates to a pressure equalizing insert (1) which is provided for installation in a valve (10) for regulating a fluid stream in particular in a HVAC system. The pressure equalizing insert (1) comprises a housing (2) having an actuating member (3) which is movably mounted thereon and is configured to at least partially guide the fluid stream regulated by the valve (10) and, when the pressure equalizing insert (1) is installed, co-operates with a valve seat (15) depending upon a pressure difference prevailing in the fluid stream in order to regulate the fluid stream. The invention further relates to a valve (10) having an installed pressure equalizing insert (1), wherein the pressure equalizing insert (1) can be inserted in particular as a pre-assembled assembly into the valve (10).
