摘要:
A hydraulic system for controlling the engagement and disengagement of a friction element includes a source of line pressure, a source of exhaust pressure, a manual valve having a forward state and a reverse state, connected to the exhaust pressure source and line pressure source and including a first outlet and a second outlet, for opening and closing communication between said outlets and said pressure sources in response to changes in the states, a friction element communicating with the line pressure source through the manual valve in the reverse state, and a control valve including a port communicating with the friction element, the control valve producing control pressure at the port when the manual valve is in the forward state.

摘要:
In accordance with the present invention a paint can having a bottom and an integrally formed side wall portion, having a top portion having an inwardly extending rim portion containing a plurality of spaced openings therein of sufficient size to return any paint which flows into the rim into the paint can. The openings are preferably placed on only one side of the rim so that the other side of the rim can be used for pouring without paint being spilled through the openings. The openings may be circular, square, rectangular, polygon eliptical, or any other convenient shape so long as they have sufficient size to avoid surface tension causing the paint to fill the opening and prevent flow back into the can.
