SANITARY INSERT UNIT

摘要

The present disclosure is directed to a sanitary insert unit, configured for insertion into a discharge fitting. The insert unit includes an upstream sieve connected to a throughflow regulator. The throughflow regulator includes a control gap and a throttle body that deforms under pressure to regulate throughflow by varying an opening size of the control gap. The sieve and throughflow regulator are arranged upstream of a jet diffusor which includes a plurality of radial openings. The sieve, throughflow regulator and jet diffusor are arranged to be, at least partially, received within a housing. The ratio of the overall height of the insert unit to the height of the height of the assembled sieve and throughflow regulator is approximately 2.7:1.

1. A sanitary insert unit (101, 201, 301), configured for insertion into a discharge fitting, comprising:
an upstream sieve (102, 202, 302) connected to a throughflow regulator (103, 203, 303), which comprises a control gap (110, 210, 310) and a throttle body (108, 208, 308) which regulates throughflow by varying an opening size of the control gap (110, 210, 310), the sieve (102, 202, 302) and throughflow regulator (103, 203, 303) are arranged upstream of a jet diffusor (104, 204, 304) which comprises a plurality of radial openings (120, 220, 320) in a throughflow direction; the sieve (102, 202, 302), throughflow regulator (103, 203, 303) and jet diffusor (104, 204, 304) are arranged to be, at least partially, received within a housing (105, 205, 305), wherein a ratio of the overall height of the insert unit (101, 201, 301) to the height of the height of the assembled sieve (102, 202, 302) and throughflow regulator (103, 203, 303) is in a range between 2.5:1 to 4:1.
