Abstract
A homogenizer comprises a homogenizing valve mounted to a pump block. Sets of three suction valves and discharge valves are positioned in valve bores in opposite faces of the block. Each of the valve bores has a hemispherical termination. The hemispherical termination of a pump chamber is formed in an adjacent surface of the block and is in communication with the valve bores through oblique conduits. The pump cylinder is formed in a packing box mounted in the block by bolts extending through the block. Integral valve assemblies removable as units are positioned in the valve bores. A pressure sensor is coupled to a discharge manifold through an isolating piston.

A pump comprising:
- a block;
- a pump chamber having a hemispherical termination formed through a first surface of the block along a pump axis;
- a suction valve bore having a hemispherical termination formed through a second surface of the block along a suction axis angled relative to the pump axis;
- a one-way suction valve assembly positioned in the suction valve bore;
- a discharge valve bore having a hemispherical termination formed through a third surface of the block along a discharge axis angled relative to the pump axis;
- a one-way discharge valve assembly in the discharge valve bore;
- a suction conduit radially intersecting the hemispherical termination of the suction valve bore and the hemispherical termination of the pump chamber;
- and
- a discharge conduit radially intersecting the hemispherical termination of the discharge valve bore and the hemispherical termination of the pump chamber.

A pump comprising:
- a block:
- a suction manifold extending through the block;
- a set of suction valve bores, each having a hemispherical termination, formed through the block to intersect the suction manifold;
- a one-way suction valve assembly positioned in each of the suction valve bores;
- a discharge manifold extending through the block;
- a set of discharge valve bores, each having a hemispherical termination, formed through a surface of the block opposite to the suction valve bores to intersect with the discharge manifold;
- a one-way discharge assembly positioned in each of the discharge valve bores;
- a set of pump chambers, each comprising a cylinder formed in a packing box fixed to the block, the cylinders extending at right angles to the suction and discharge valve bores, the termination of each cylinder being a hemispherical cup in the surface of the block, each packing box being mounted to the block by means of bolts extending through the block;
- a suction conduit radially intersecting the hemispherical termination of each suction valve bore and the hemispherical termination of a corresponding pump chamber at oblique angles relative to the pump chamber and to the suction valve bore;
- and
- a discharge conduit radially intersecting the hemispherical termination of each discharge valve bore and the hemispherical termination of a corresponding pump chamber and extending at oblique angles relative to the pump chamber and to the discharge valve bore.
