LIQUID DISTRIBUTING VALVE

摘要

A liquid distributing valve includes a housing, an oil supply passage, an oil storage valve and a two-position three-way valve. The oil storage valve is separated into an oil storage chamber and an oil pressing chamber by a piston, and the oil storage chamber is in communication with an oil discharge port and has a spring pressing against the piston. The two-position three-way valve includes a valve body cavity having an oil inlet in communication with the oil supply passage, a valve core and a valve seat having a core hole in communication with the oil storage chamber via a bypass oil passage. When the valve core is at one position, the oil inlet is blocked off, and the oil pressing chamber is in communication with the oil storage chamber. When the valve core is at another position, the core hole is blocked off, lubricant enters the oil inlet.

1. A liquid distribution valve, comprising at least one housing, an oil supply passage, and at least one oil storage valve and at least one two-position three-way valve both using a respective inner cavity of the housing as carrier, and each oil storage valve corresponding to one two-position three-way valve; a valve chamber of the oil storage valve being separated into an oil storage chamber and an oil pressing chamber by a piston, and the oil storage chamber being in communication with an oil discharge port and having a spring pressing against the piston; wherein the oil supply passage is arranged inside the housing; the two-position three-way valve comprises a valve body cavity, a valve core and a valve seat, the valve body cavity is in communication with the oil pressing chamber via an oil exchanging passage, the valve body cavity has an oil inlet in communication with the oil supply passage, and the valve seat has a core hole in communication with the oil storage chamber via a bypass oil passage;
in a case that the valve core is at a first valve position, the valve core blocks off the oil inlet, and the oil pressing chamber is in communication with the oil storage chamber through the oil exchanging passage, the valve body cavity, the core hole and the bypass oil passage; and in a case that the valve core is at a second valve position, the valve core blocks off the core hole, and the oil inlet is in communication with the oil pressing chamber via the valve body cavity and the oil exchanging passage.
