Filed:

Aug 30, 1994

Appl. No.:

8/297801

Inventors:

Walter W. Powell - Sugar Land TX
Milton N. Anderson - Houston TX

Groth Corporation - Houston TX

International Classification:

F16K 17196

US Classification:

137488

Abstract:

A safety relief valve (10) having a main valve member (22) in a normally closed seated position has a diaphragm actuator (24) with a dome chamber (34) adjacent the outer side of the diaphragm (26). A pilot valve (28) is in fluid communication with the dome chamber (34) through a dome line (35) for controlling the opening and closing of the main valve member (22). An underdome chamber (40) on the inner side of the diaphragm (26) has an underdome line 44 extending to an underdome control valve (42) for controlling fluid communication to underdome chamber (40) from the inlet (18). An inlet line (48) extends from the inlet (18) to the underdome control valve (42). When the set pressure of the pilot valve (28) is reached, inlet fluid pressure on the inner side of the diaphragm (26) increases while dome pressure in the dome chamber (34) decreases. Simultaneously, an increase in fluid inlet pressure at inlet (18) actuates underdome control valve (42) to provide direct fluid communication between inlet (18) and underdome chamber (40) to boost the opening of main valve member (22). One embodiment of the invention shown in FIGS.

Appl. No.:

8/058422

Inventors:

Groth Corporation - Houston TX

International Classification:

F16K 3122

US Classification:

137192

Abstract:

A vertically oriented float assisted automatic driptrap mechanism having a float valve chamber defined by a body section and base is disclosed. A float is located for vertical liquid level responsive movement within the float valve chamber and reciprocates within a valve stem float guide. A diffuser is provided at the inlet of the chamber to prevent impingement of incoming fluid on the float. The valve stem guide also serves as a filter support for a filter which filters out contaminants that might interfere with the valving action of the driptrap mechanism. A valve seat having a tapered seat surface and a self-positioning valve plug movably supported by the valve stem and having a differently tapered sealing surface establish line contact sealing to ensure effective valve operation under high pressure conditions.

International Classification:

F04B 27/10
F01B 3/00

Abstract:

A variable stroke high pressure pump is disclosed. The pump uses a wobble plate design with dynamically variable tilt to provide continuous adjustment of pump stroke length and output. Dynamically variable tilt is accomplished using a linearly actuated tilt thruster rotationally coupled to the drive shaft to maintain a selected tilt of the wobble plate through the rotation of the wobble plate.
