Abstract

pressure regulator (10) having a housing (12, 14) with an inlet (16), an outlet (22) and a valve seat (52), a regulator sleeve (30) arranged within the housing (12, 14) and defining a flow channel from an upstream end adapted for cooperating with the valve seat (52) towards a downstream end associated with the outlet (22), a spring (48) biasing the regulator sleeve (30) towards the outlet (22), the downstream end of the flow channel tapering outwardly in the downstream direction. The housing is formed from a hollow body (12) closed by a cover piece (14). The guiding insert (40) is provided at the upstream side of the regulator sleeve (30) and is slidably arranged on the outer circumference of a cylinder (32) of the regulator sleeve (30). With its radially outer surface, the guiding insert (40) is accommodated within a recess (42) provided in the cover piece (14). The recess (42) of the cover piece (14) is provided with a protrusion (43) behind which the guiding insert (40) engages.

Description

Amended abstract for response to ER3 A pressure regulator (10) having a housing (12, 14) with an inlet (16), an outlet (22) and a valve seat (52), a regulator sleeve (30) arranged within the housing (12, 14) and defining a flow channel from an upstream end adapted for cooperating with the valve seat (52) towards a downstream end associated with the outlet (22), a spring (48) biasing the regulator sleeve (30) towards the outlet (22), the downstream end of the flow channel tapering outwardly in the downstream direction. The housing is formed from a hollow body (12) closed by a cover piece (14). The guiding insert (40) is provided at the upstream side of the regulator sleeve (30) and is slidably arranged on the outer circumference of a cylinder (32) of the regulator sleeve (30). With its radially outer surface, the guiding insert (40) is accommodated within a recess (42) provided in the cover piece (14). The recess (42) of the cover piece (14) is provided with a protrusion (43) behind which the guiding insert (40) engages.
The pressure regulator serves for ensuring a generally constant pressure on the consumer side of the water supply system where the water tap is provided, without there being much noise when the regulator sleeve is placed within the housing of the pressure regulator while the water is flowing through the flow channel within the regulator sleeve.
