摘要： The present invention relates to a flat slide valve characterized in that a pair of spacers and a slide board having connecting ports and pressure balancing holes are fitted intimately between two guide plates having valve holes and pressure balancing holes, with the thickness of said slide board being formed slightly thinner than that of the spacers, and that the pressure balancing holes for preventing augmentation of controlling power of the slide board by fluid pressure are formed in communication with the corresponding valve holes in said two guide plates and said spacers.

摘要： A valve construction includes a cylinder having an inlet fitting at one end and an outlet fitting at an opposite secondary end and being divided internally into an inlet chamber portion adjacent the inlet end and an outlet chamber portion adjacent the outlet end. A nozzle-shaped member is disposed in the outlet chamber and urged in a direction by a washer element toward the inlet end so that its nozzle points into the inlet chamber. The nozzle member defines an interior passage which may be closed by a poppet portion of a slide valve member which, in the nonactuated position is urged by a spring toward the inlet end into a position at which it opens the passage to the nozzle member. An electromagnetic coil is provided to cause movement of the valve member which is formed as a magnetically attractable armature so that it will move downwardly with the poppet member carried thereby in accordance with the primary pressure exerted through the inlet to overcome the biasing force of the spring and to at least partially close the passage of the nozzle member. A portion of the inlet flow is divided at the nozzle member and flows around the nozzle member into an annular passage defined therearound at the outlet chamber and which is sealed by a lip shaped tacking. During the primary pressure flow conditions, a portion of the liquid will pass around the packing and exit out through the outlet wherein an excessive pressure will cause an annular flange member to move upwardly to seal the connection between the outlet and inlet passages which is formed around the nozzle member.
