Abstract
Abstract A crosshead arrangement for a high-pressure compressor or pump having opposed cylinders consisting of two principal parts, of which one carries a main and a secondary crosshead shoe and a crosshead pin member, to which the piston rod of one of the cylinders is releasably connected, is disposed as a middle part between the two principal parts in the region of the main crosshead shoe. A second member, without crosshead pin may be disposed between the two principal parts in the region of the secondary shoe and be releasably connected to the piston rod of the other cylinder.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
121 words
A high-pressure compressor machine having a drive mechanism comprising a cross-head frame, a first and a second opposed cylinder each having a piston and piston rod connected to said frame, a crosshead arrangement in said frame located between said cylinders comprising a lower part, a main crosshead guide and a secondary cross-head guide spaced from one another and mounted on said lower part, an upper part, means accessible from the top surface of said upper part for releasably connecting said upper part to said lower part, a crosshead pin member forming a middle part of said main crosshead guide located between said lower and upper parts and means connecting said pin member releasably to the piston rod of said first cylinder.
Claim 2
Dependent Claim
121 words
A high-pressure compressor machine having a drive mechanism comprising a cross-head frame, a first and a second opposed cylinder each having a piston and piston rod connected to said frame, a crosshead arrangement in said frame located between said cylinders comprising a lower part, a main crosshead guide and a secondary cross-head guide spaced from one another and mounted on said lower part, an upper part, means accessible from the top surface of said upper part for releasably connecting said upper part to said lower part, a crosshead pin member forming a middle part of said main crosshead guide located between said lower and upper parts and means connecting said pin member releasably to the piston rod of said first cylinder.
Claim 3
Dependent Claim
43 words
A high-pressure compressor machine according to claim 1 wherein a second, plain, middle part is arranged between said lower and upper parts adjacent said secondary crosshead guide and means connecting said second middle part releasably to the piston rod of said second cylinder.
Claim 4
Dependent Claim
28 words
A high-pressure compressor machine according to claim 1 wherein said connecting means connects said upper part and said lower part to one another adjacent said secondary crosshead guide.
Claim 5
Dependent Claim
41 words
A high-pressure compressor machine according to claim 2 wherein said cylinders are horizontal and said middle parts are connected to said upper and lower parts at both sides of said crosshead frame by said connecting means which comprises vertical screw-threaded members.
Claim 6
Dependent Claim
26 words
A high-pressure compressor machine according to claim 2 wherein force-transmitting adjustable elements are interposed between said middle parts and said upper part and said lower part.
Claim 7
Dependent Claim
35 words
A high-pressure compressor machine according to claim 5 wherein said force-transmitting elements are interposed between said middle parts and said upper and said lower parts adjacent said main crosshead guide and said secondary crosshead guide.
