摘要： A transmission housing having a modulatable power transmission therein which includes a clutch having interleaved clutch plates and having a central power transmitting shaft extending axially through the clutch. The clutch includes a fluid operated movable piston for effecting clutch operation by compression of the plates. The piston has a smaller piston area and a larger piston area, the smaller piston area has fluid flow directed to it at a variable fluid pressure whereby the clutch is modulatable. The larger piston area is adapted to have fluid flow directed thereto to effect maximum and unmodulatable engagement of the clutch. A spring loaded normally closed trigger valve controls fluid flow to the larger piston area in response to fluid pressure above a predetermined amount at the smaller piston area. The trigger valve is mounted on the outside of the transmission housing and is readily accessible for adjustment, for example. The trigger valve is normally closed so that pressure fluid is directed to the smaller piston area at a variable fluid pressure whereby the clutch is modulatable. When the valve is open by fluid pressure over a predetermined amount, the valve permits fluid flow to the larger piston area to effect maximum and unmodulatable engagement of the clutch for full clutch capacity.

摘要： The present invention is a pressure regulator for regulating a fluctuatable fluid pressure of a fluid flow, the fluid flow being received from a first device and being transmitted to a second device, including a spool valve being translatable between a closed non-regulating disposition and an open regulating disposition, a throttled portion of a fluid flow acting on a first spool working surface and a main portion of the fluid flow acting on a second opposed spool working surface. A method of regulating a fluctuatable fluid pressure is further included.
