Patent number: 6877714Abstract: A flow control valve having a valve member engageable with a valve seat. The valve opens when the valve member disengages the valve seat as fluid pressure is bled from a pressure chamber on one side of the valve member. The valve closes after the pressure bleed ends when fluid pressure is metered back into the pressure chamber through a metering path. The speed at which the valve member closes is selectable depending upon the degree to which the metering path is tortuous. Two different tortuous configurations of the metering path are provided by two differently shaped labyrinths. The user can select one closing speed or the other by choosing which labyrinth is in the metering path.Type: GrantFiled: May 8, 2003Date of Patent: April 12, 2005Assignee: The Toro CompanyInventor: Leslie R. Hall

Patent number: 6868868Abstract: A manifold body allows a pressure-control knob to be disposed facing in a selected direction. The manifold body is divided into a manifold block and a regulator block. The manifold block is provided with a pressure gauge, an inport, and an outport. The regulator block is provided with a pressure-control knob and a regulator. The manifold block and the regulator block have respective fitting portions that are at an angle of 45 degrees to a mounting surface as seen in the side view. Each fitting portion is symmetric with respect to a center axis, so that the regulator block can be joined to the manifold block at either of two different angles.Type: GrantFiled: January 9, 2003Date of Patent: March 22, 2005Assignee: SMC CorporationInventor: Masayuki Okitsu

Patent number: 6834661Abstract: A control valve system includes a housing having an inlet port, a first output port, a second output port, and a valve chamber. A primary spool and a secondary spool are independently slidable in the valve chamber. The secondary spool has a first end for abutting against the primary spool and has a second end with a working surface area greater than the working surface areas at the ends of the primary spool. A solenoid valve assembly controllably connects the inlet port to the second end of the secondary spool. A biaser provides a biasing force to the primary spool. A first fluid passage through the primary spool provides fluid communication between the first output port and a second end of the primary spool for displacing the primary spool relative to the secondary spool in an energy saving mode, thereby regulating a pressure at the first output relative to the predetermined magnitude of the biasing force.Type: GrantFiled: July 18, 2003Date of Patent: December 28, 2004Assignee: Ross Operating Valve CompanyInventor: José Carlos Bento

Patent number: 6802334Abstract: In a method of manufacturing different types of water and sanitary fitting elements, such as taps and mixers, there is used multiple functional parts that have parts which come into contact with water in use, and one or more casing parts which are at least partially visible. The water-contacted functional parts are formed in a module system that includes a limited number of elements, e.g. 10-15 in number, and are made of a material that will not deliver harmful substances to the water. The casing parts are made of another material and are given an inner shape or form which is adapted to the outer shape or form of the functional parts so the casing parts will surround the functional parts, either completely or partially, in an exchangeable manner. The functional parts may be made of a plastic material, e.g., a thermoplastic material, while the casing parts may be made of any chosen material. Also provided is a module system built-up of functional parts and casing of the aforesaid kind.Type: GrantFiled: April 2, 2003Date of Patent: October 12, 2004Assignee: FM Mattsson ABInventor: Stefan Ericsson
