changes!. Thus, in the chambers where the clearance .at output ip
decreased, the flow rate is also decreased and, together with this,
• esistance is reduced during the flow of lubricant through the
discharging jet, and vice versa. Allthis gives rise to a pressure
increment in
some chambe s, and to a reduction inothers, which
preates' the t carrying capacity which balanceq the external load.
