Patent number: 6755204Abstract: A land (56) on an index member (32) disposed in the interior chamber of a manifold (38) is aligned with an actuating member (34) and thereby holds open a check valve (36) through which fluid flows into the manifold's interior chamber, through a control valve (12), and out a manifold outlet (74). At the same time, another actuating pin (42) is so aligned with a recess (58) in the indexing member (32) as to permit another check valve (44) to prevent flow through itself into the manifold chamber. When the control valve is closed, flow stops, and pressure builds up in the manifold chamber. The index member (32) is accordingly driven against the force of a bias spring (48) to a lower position, in which a lower cam-follower surface (82) engages a lower cam surface (84). That engagement rotates the index member to a position in which it permits pressure to be communicated through both check valves (36 and 44) into the manifold chamber.Type: GrantFiled: March 4, 2002Date of Patent: June 29, 2004Assignee: Arichell Technologies, Inc.Inventors: Kay Herbert, Natan E.

Patent number: 6240949Abstract: A three-way valve is configured as a solenoid operated diverter when the solenoid is used in parallel with a poppet valve. When the diverter is in a first mode, hydraulic fluid entering a first port exits the valve through a system outlet port while hydraulic fluid entering a second port exits through a second port. The solenoid valve is positioned to close the second port when energized in order to shift the system to a second mode. When the solenoid valve is energized to close the second port so that all of the fluid entering the second port opens the poppet valve and exits through the system outlet. By utilizing a poppet valve in parallel with a solenoid valve rather than a valve spool, the three-way diverter is able to operate at higher pressures and higher fluid flow because Bernoulli effects which cause closing of valve spools used in prior art three-way valves do not adversely affect the poppet valve.Type: GrantFiled: January 20, 2000Date of Patent: June 5, 2001Assignee: Parker-Hannifin CorporationInventor: Gerald Ross Gerstenberger
