Patent number: 6209802Abstract: A spinning wash nozzle assembly having a fluid brake pump within the rotating spinner housing. The fluid pump has a sump which is also within the rotating spinner housing such that centrifical forces acting on the fluid tend to separate the heavier fluid from any air within the sump. As a result, only the fluid is drawn into the pump as opposed to fluid and air. This avoids undesirable effects on the pump from air being drawn therein.Type: GrantFiled: May 12, 2000Date of Patent: April 3, 2001Assignee: InterClean Equipment, Inc.Inventor: Erkki A. Koivunen

Patent number: 6071208Abstract: An automatic transmission for motor vehicles comprising three interconnected planetary gear units, two rotating friction clutches and four friction brakes providing six optimized forward gear ratios and a reverse ratio, all assembled into a compact package no larger than the current four-speed automatic transmissions.

Patent number: 6029785Abstract: A force balanced brake system for effecting ratio changes in transmission comprising a band brake unit (10) having separate bands (12 and 13) selectively engageable with a reaction drum (5), each with a piston apply lug (16 and 18) and anchor lug (17 and 19). With equal area apply pistons (21 and 41 charged with common pressure, apply and reaction forces are equal and opposite. Side loads are eliminated so the brake drum (5) is only piloted as a rotating component. The system provides freewheeler type shifts without specific one-way devices. The brake band unit (10) provides engine braking during vehicle coast. For freewheeler type shifts, the system is staged in a one-way mode and the torque capacity of the band is regulated to vary in direct relationship with the torque band (10) also reduces to a near zero value allowing the brake drum (5) to turn freely in the direction opposite to previous reactive torque.Type: GrantFiled: January 12, 1998Date of Patent: February 29, 2000Inventor: Erkki A. Koivunen
