Patent GB-2152141-A (GB)
Title: Rotary high pressure, low capacity pump
Inventor: ETSION IZHAK
IPC: F04D5/00
Filed: 1983-12-30
Abstract: The pump comprises a rotor (3) having a smooth, planar, circular surface rotating in a casing (1) provided with a stator surface (21) adjacent the rotor surface. The stator surface (21) is in the shape of a circular, flat-topped ridge having its center displaced with respect to the rotor center. The circular ridge has a different height on both sides of the diametral line through the rotor centre, creating a respective narrow gap (h) and a wide gap (H) between the ridge and the rotor surface. A fluid inlet (11) is provided in the casing outside the circular ridge and a fluid outlet (22) is provided inside the ridge. Owing to the eccentricity of the ridge with respect to the rotor more fluid is drawn by the drag of the rotor surface into the space defined by the stator ridge through the wide gap than escapes through the narrow gap, whereby the pressure increases inside the ridge and drives the fluid out through the fluid outlet. The direction of rotation of the rotor may be reversed to pump fluid in the opposite direction. <IMAGE>

IPC: F01L3/10
Filed: 1986-01-31
Abstract: In a valve assembly comprising a valve closure member (1) having an elongate stem (5) with at least two gripping members (15) which partially define a cavity (19) which is open at one axial end (21), an end (13) of the valve stem (5) extends through the open end (21) of the cavity (19) and is gripped by sections of the respective gripping members (15) which define the open end (21) of the cavity (19), the gripping members (15) defining an outer tapered surface which is engaged by an annular clamp member (31).
