<p>According to an aspect of the invention, a valve (1) for controlling supply of grease is provided. A gap (140) is defined between a circumference of a closing member (130) and an inner wall of a chamber (105) for admitting a flow of grease when the closing member moves between a closed position and an open position. Further, a passage (135) extends through the closing member and/or in the housing for admitting a flow of grease between opposite sides of the closing member when the closing member moves between the closed and open positions. The valve is adapted such that a flow of grease occurs in the gap when the closing member moves towards one of the closed and open positions, which flow is larger than a flow of grease in the gap occurring when the closing member moves towards the other one of the closed and open positions. A circulation of grease is created in the chamber for reducing accumulation of grease in dead spaces.</p> |
