摘要： A manually operable high pressure release valve in a high fluid pressure system such as an air operated hydraulic pump. The release valve includes a manually operable pilot poppet valve disposed within a larger, manually operable poppet valve, the two poppet valves having a single manual actuator. Release of high pressure is allowed with a minimum of manual effort by first bleeding off a portion of the fluid under high pressure through opening of the pilot poppet valve until the pressure is reduced to a level whereat the larger poppet valve will easily open.

摘要： A feed and proportioning pump is provided for delivering two different liquids in a given proportion by flow volume, and in particular to a pump for delivering fuel and oil to mixturelubricated combustion engines, having two interconnected displacement members executing their suction strokes and their feed strokes simultaneously and arranged in special working chambers communicating with a suction and a delivery line by way of reciprocally acting check valves.
